Tips On Pregnancy

Are you thinking that you’re pregnant? There are women who would know shifts are developing to their physique regardless of how slight. But also for the others, they would not know they are having a baby until it is apparent. It’s appealing that women would display different indicators when they’re pregnant. The list below can help you evaluate if you are having a baby or not and what you must do.

Signs and Symptoms of Pregnancy

• Very early, there’s that feeling of being tired more than usual. You would get this sort of feeling even if the pregnancy is just 7 days old. This is related to the rise of progesterone, a hormone associated with the female reproductive system.

• Pregnancy will make you feel dizzy, nauseous and some slight disinclination to specific dishes. These are all because of the hormonal shifts happening in your body. You may want to entertain the possibility that all these aches and annoyances will remain with you up until you have delivered your child.

• A missed menstrual cycle is the most evident symptom of pregnancy. However, there may also be some other reasons why you missed your period such as hormonal problems, exhaustion and everyday worries. In any case, it would be better to seek medical advice as soon as you miss your monthly period.

• Other symptoms include constant urination, mood swings, bowel irregularity, mild to severe headaches, fainting and back pains.

How to Know If You Are Having A Baby

The hormone HCG or human chorionic gonadotropin present in urine and blood samples is an excellent marker. Its presence can be measured after Ten days of being pregnant. A measurable amount of blood serum can indicate low HCG number when you are pregnant. Only in instances of high HCG number can urine samples indicate pregnancy.

A different way to test if you’re having a baby is EPF, or early pregnancy factor. EPF can determine pregnancy as quickly as 48 hours. The EPF however, can be a bit pricey and takes lengthier to get results.

Pregnancy Diet Program

It is recommended that you get as much folate, calcium, zinc, dietary fiber and iron in your body. A good amount of folate consumption lessens neural tube defects in your baby up to 70 percent. You can get this from legumes, fruits and citrus juices for around 300 micrograms. Various other sources of folate are whole grain products, chicken, pork and seafood.

Calcium daily consumption would be about 1,200 milligrams. You can get your calcium mineral from a whole variety of dark green veggies, soy and low-fat dairy products and orange juice. Calcium enhances the bone growth of your baby and strengthens your bones also. Further support by increased blood volume level can be achieved with iron intake. Iron rich foods and vitamin supplements can provide you with the necessary 30 milligrams a day.

Try to avoid uncooked meat to lessen the risk of bacterial illnesses just like salmonella and listeria, in which the latter is found in certain cheese types.

Other Recommendations On Being Pregnant

There needs to be a balance of your physical and mental wellbeing. Allow yourself ample time to rest and relax. However, make sure you do exercises designed to help make your body stronger as it conditions itself for the birth of your baby.

Do not starve yourself by not having food for over 2-3 hours. Balanced food consumption helps maintain blood glucose to acceptable levels. Stay hydrated by drinking lots of fluids. This can reduce constipation as well as reducing the chance of preterm labor.

Informative Pregnancy Tips And Helpful Information

Helpful Pregnancy Tips That Will Prove Useful

It is important that you understand all you can about pregnancy, considering you will be caring for another life. You can go over a lot of insightful tips here in this article. That way, you can feel more at ease when you’re thinking of what steps to take during your pregnancy.

Check out the hospital ahead of your delivery. Explore the facility and chat with the staff. This can help to alleviate a lot of nervousness and provide a good opportunity for you to ask questions. This is especially helpful for expectant dads since they will do the majority of the communication with hospital staff.

Keep exercising, unless your doctor tells you to stop. There are plenty of exercises you can safely benefit from like walking, swimming or low-impact aerobics. They make for a healthier heart and stronger core muscles, which may minimize back pain and make delivery a bit easier on you.

For those who experience constipation during pregnancy, try to eat foods that are high in fiber, such as fruits, vegetables and whole wheat bread and cereals. The hormones in your body during pregnancy is the cause of the constipation. Constipation can cause pregnant women to have extreme gastrointestinal problems. In addition, it’s just not a pleasant feeling.

If you struggle with constipation, add foods that contain lots of fiber to your diet. Constipation is caused by hormones produced by a pregnant woman. Constipation can cause some gastrointestinal issues for someone who is pregnant, and it does not feel very good.

Are leg cramps keeping you up at night? If you start having leg cramps during your pregnancy, you should first make sure that you are drinking enough water during the day. When you first get into bed, do some leg stretches to help your muscles relax. Bananas contain potassium, which can help with cramps as well.

Look for maternity clothes from thrift and consignment shops. You won’t be wearing these clothes for long, so don’t pay full price. You want to save money and aid the environment via reducing the negative effects associated with shipping and producing new clothes.

One of the myths associated with pregnancy is that you can’t work out while expecting. Even though you should not exercise heavily late in your pregnancy, studies show that if you are physically fit, it usually results in a much less labor intensive pregnancy.

You can eat junk food once in a while, but not too often while pregnant. There are reasons your body craves certain foods; you may need specific nutrients those foods can supply. Eating for two causes your body to go through nutrients and energy faster than usual, so don’t feel guilty indulging your cravings.

To help you be able sleep through the night plan your water consumption out carefully. Keep up your water intake before dinner, but lay off the water once you eat, and don’t drink any right before you go to sleep. This will help reduce the need to get up during the night to use the restroom.

Change your habits and your diet for the better as soon as you start trying to become pregnant, or as early as possible in your pregnancy. If you eat healthy food, you will be as healthy as possible throughout your pregnancy. It will also make your baby accustomed to healthy foods.

Take a full tour of where you’ll give birth. This can help you see what it looks like, especially if this happens to be your first pregnancy. That ensures you don’t panic when you’re in labor.

Visit the hospital you plan on giving birth in. Tour the facility and become acquainted with the staff. Doing this can help you relax because you will become more familiar with the place where you will be giving birth. In addition, all of your questions about the birthing process can be answered. Dads should do this, especially since they are going to be the principal communicator that day when you go into labor.

Don’t use hot tubs or saunas while you are pregnant. High temperatures are not good for your pregnancy. Common spa treatments often incorporate essential oils, which can cause complications and contractions early in pregnancy. Specifically avoid clary sage, juniper, or rosemary oil.

Those who are pregnant should be careful in the sun. Skin can become sensitive and rough when pregnant, so take care of it accordingly.

Regular dental visits and daily oral hygiene are important during pregnancy. Being pregnant can actually cause you to develop dental problems, such as gingivitis. Be certain to keep brushing two times a day, floss and use mouthwash. If there are any issues, make sure to get in touch with your dentist.

Now that you know more about what to expect, you can start to feel a little more at ease. Pregnancy is great and special, but it’s also difficult. This article has provided you with tips to help make your experience go much more smoothly.

A pregnancy test may let you know if you are pregnant.

Here are answers to some of the most common questions about pregnancy tests.

What is a pregnancy test, and how does it work?

Pregnancy tests are designed to tell if your urine or blood contains a hormone called human chorionic gonadotropin (hCG). This hormone is made right after a fertilized egg attaches to the wall of a woman’s uterus.

This usually happens — but not always — about 6 days after fertilization. If you’re pregnant, levels of hCG continue to rise rapidly, doubling every 2 to 3 days.

What types of pregnancy tests are available?

Two main types of pregnancy tests can let you know if you’re pregnant: urine tests and blood tests.

Urine tests can be done at home or in a doctor’s office. Many women first choose a home pregnancy test to take about a week after a missed period. Home pregnancy tests are private and convenient.

These products come with instructions. Follow them closely for the most accurate results. After testing, you can confirm results by seeing your doctor, who can perform even more sensitive pregnancy tests.

Blood tests are done at your doctor’s office, but are used less often than urine tests. These tests can detect pregnancy earlier than a home pregnancy test, or about 6 to 8 days after ovulation. But with these tests, it takes longer to get the results than with a home pregnancy test.

Two types of blood pregnancy tests are available:

A qualitative hCG test simply checks to see if hCG is present. It gives a “yes” or “no” answer to the question, “Are you pregnant?” Doctors often order these tests to confirm pregnancy as early as 10 days after a missed period. Some of these tests can detect hCG much earlier.

A quantitative hCG test (beta hCG) measures the exact amount of hCG in your blood. It can find even very low levels of hCG. Because these pregnancy tests can measure the concentration of hCG, they may be helpful in tracking any problems during pregnancy. They may also (in combination with other tests) be used to rule out a tubal (ectopic) pregnancy or to monitor a woman after a miscarriage when hCG levels fall rapidly.

How accurate are pregnancy tests?

Waiting at least a week after a missed period may give you the most accurate result. Results may also be more accurate if you do the test first thing in the morning, when your urine is more concentrated.

Urine home pregnancy tests are about 99% accurate. Blood tests are even more accurate than this.

How accurate a home pregnancy test is depends upon:

  • How closely you follow instructions.
  • When you ovulate in your cycle and how soon implantation occurs.
  • How soon after pregnancy you take the test.
  • The sensitivity of the pregnancy test.

Is it expensive or hard to do a home pregnancy test (HPT)?

You can buy a home pregnancy test in a drugstore without a prescription. The cost depends on the brand. But most tests are relatively inexpensive — from $8 to $20.

Home pregnancy tests are quick and easy to use. They are also very accurate if you carefully follow directions. These pregnancy tests all work in a similar way. You test the urine in one of these ways:

  • Hold the test’s stick in your urine stream.
  • Collect urine in a cup and then di p the test’s stick into it.
  • Collect urine in a cup and use a dropper to put urine into another container.

With all of these techniques, you need to wait a few minutes before seeing the results. Results may show up as a line, a color, or a symbol such as a “+” or “-” sign. Digital tests produce the words “pregnant” or “not pregnant.”

If you have any questions about the pregnancy test or the results, call your doctor or the telephone number listed with the home pregnancy test.

What do the pregnancy test results mean?

It’s important to know what a positive or negative result means.

If you get a positive result, you are pregnant. This is true no matter how faint the line, color, or sign is. If you get a positive result, you may want to call your doctor to talk about what comes next.

In very rare cases, you can have a false-positive result. This means you’re not pregnant but the test says you are. You could have a false-positive result if blood or protein is present in your urine. And certain drugs, such as tranquilizers, anti-convulsants, or hypnotics, may also cause false-positive results.

If you get a negative result, you are likely not pregnant. However, you may still be pregnant if:

  • The test is past its expiration date.
  • You took the test the wrong way.
  • You tested too soon.
  • Your urine is too diluted because you drank large amounts of fluids right before the test.
  • You are taking certain medications, such as diuretics or antihistamines.

If you get a negative pregnancy test result, try retesting within about a week to double-check. Some home pregnancy tests suggest doing this regardless of your results.

What if you get two different results? Call your doctor. A blood test is a good idea to confirm results.

When to take pregnancy test after ovulation calculator

Ovulation Tests – or Ovulation Predictor Kits – allow you to predict, with great accuracy, your most fertile time of the month. Easy to use, OPKs can greatly increase your chances of becoming pregnant – if you use them correctly. Let our Ovulation Test FAQ help you enhance your predictive success!

If used correctly, ovulation tests are excellent predictors of ovulation. However, in order to detect the LH surge with accuracy, directions must be followed exactly. The most common mistake made with OPKs is generalizing the methods of pregnancy testing to ovulation testing – which leads to errors in use and in the interpretation of results. To get the most out of ovulation testing, read our Ovulation Test FAQ.

Q: How do ovulation tests work?

Ovulation tests detect luteinizing hormone (LH). Just prior to ovulation, women experience a brief surge in luteinizing hormone. Ovulation predictor kits help you pinpoint this surge and anticipate ovulation – your most fertile period in your cycle. Luteinizing hormone, in elevated amounts, is actually the hormone that causes you to ovulate (when the eggs bursts from the ovarian follicle), so that is why lh tests are so effective in anticipating your most fertile time.

Q: How do I interpret results? The same as pregnancy tests?

Ovulation tests function differently than hCG pregnancy tests. A positive result (indicating an LH Surge) is indicated by a test band that is of equal or greater intensity (equal or darker) than the control band. A negative result for the LH Surge is indicated when the test band is of lesser intensity (lighter) than the control band or cannot be seen. Click here to see diagrams of test results.

Q: What is the best time of day to take the ovulation test?

Unlike pregnancy tests, morning (first morning urine) is not the best time to collect samples for ovulation tests, as LH is synthesized in your body early in the morning and will not appear in your urine until the afternoon. The ideal time to test is in the afternoon, around 2pm, though testing may safely take place from 10am to early evening.

Q: Should I take the test the same time every day?

Yes, be sure to test at the same time each day. Also, reduce your liquid intake around 2 hours before testing as a diluted liquid sample can prevent or hinder LH detection.

Q: When should I beginning testing with the ovulation predictor kit?

To determine when to start testing, you must first determine the length of your menstrual cycle. The length of the menstrual cycle is the number of days from the first day of menstrual bleeding to the day before bleeding begins on the next period. Determine the usual length of the menstrual cycle over the last few months. Then, refer to the Cycle Chart to determine on which day of the menstrual cycle to begin testing. Click Here determine when to begin testing?

Q: How long after my LH surge will ovulation take place?

Generally, ovulation will take place 12-48 hours after the LH surge is first detected (using afternoon urine samples), though 36 hours is considered to be the average length of time following the LH surge.

Q: When I get a positive on an ovulation test, when is the best time to have intercourse?

To increase the chance of conception, it is best to have intercourse the day of the LH surge as well as following three days after.

Q: Does the appearance of faint ‘test band’ indicate an LH surge?

A faint line (or a faint positive test band) does not indicate a positive result for an LH surge. While the presence of a faint line on a pregnancy test may indicate a positive result, a faint line on an OPK is always negative.

Q: Does taking my basal body temperature tell me the same thing as an OPK?

Basal Body Temperature only tells of your LH surge after it is over. That is why the BBT method cannot predict the LH surge. Ovulation tests will tell you – with pinpoint accuracy – when your chances for conception are greatest.

Q: Can OPKs be used as contraception devices?

Ovulation tests are designed to help facilitate pregnancy. They are not recommended for contraception.

Q: Can clomid interfere with test results or cause false positives?

Clomid may cause false positives if you test for ovulation too early in your cycle. Please consult with your doctor about how to use OPKs in conjunction with Clomid – or other fertility and prescription drugs.

Q: Does a light test line and a dark control line indicate a positive result?

Ovulation tests are unlike pregnancy tests – especially when it comes to interpreting results. The results are only positive if the test line is equal to or darker than the control line.

Q: I had a positive result yesterday and today. Does that mean there is something wrong?

Such results may indicate that your the tests detected the LH Surge on the way up and again on the way down.

Q: What if I experience a BBT thermal shift but the ovulation tests failed to detect my LH Surge?

It is possible to miss the surge. If you have a test line that is fairly dark one day then very light the next, you may have missed the actual surge. If your thermal shift occurs, you probably ovulated. It may be a good idea to test twice a day when you feel that you are close to ovulating. Another possibility is that you didn’t hold your urine long enough (resulting in a diluted sample).

Positive Pregnancy Test: When And How Early After Implantation?

When is the urine hCG test positive after implantation?

A blood pregnancy test is usually positive 3-4 days after implantation and a urine pregnancy hCG test is usually positive several days later or about 4-5 days after implantation.

You want to take a pregnancy test, but you have questions: How long do I have to wait after a missed period before I take a test? How long after implantation can I test? It can be confusing.

A positive pregnancy blood test first happens about 3-4 days after implantation bleeding and about 4-5 days before a missed period. T he early urine home positive pregnancy test (HPT) can usually detect pregnancy 6-7 days after implantation. Sometimes it can be as early as 2-3 days before the missed period. Implantation usually happens about 9 days (range 6-12 days) after ovulation, fertiliziation or about 8 days before the next period.

How early can I take a pregnancy test?

The Implantation Calculator will calculate for you the indivual dates of implantation as well as when to take the pregnancy test.

An early pregnancy test becomes positive only after the fertilized egg has arrived inside the uterus and implanted into the uterus and then sent enough amounts of hCG, human chorionic gonadotropin, the pregnancy hormone, into your blood stream and from there into the urine.

The urine pregnancy test (home pregnancy test or HPT) checks for the presence of the pregnancy hormone hCG in the urine. hCG is made by the implanting blastocyst and first appears in the maternal blood around implantation, on average 9 days (range: 6-12 days) after ovulation. Blood hCG levels then rise rapidly to reach a peak at 7-10 weeks. They decline after that time.

You can interactively and for free do our online pregnancy test to find out if you are pregnant or not HERE .

A negative HPT result 10+ days after the missed period makes a pregnancy unlikely. With the present generation of test kits, false-positive results due to interfering materials are extremely unlikely. Pregnancy tests have now reached a level of sensitivity and specificity that is unlikely to be surpassed either by better tests or alternative technology.

Positive pregnancy test results can show up any time before or after a missed period. Read below more about when the pregnancy test result first becomes positive.

The early urine ept HPT pregnancy test result is usually positive within 10-12 days after ovulation which is about 3-4 days after implantation

An early pregnancy test result checks for the presence of the pregnancy hormone hCG human chorionic gonadotropin in the urine.

hCg is detectable in the blood only after implantation. Implantation, the attachement of the fertilized egg to the uterus, happens on average 7-9 days after ovulation with a range of 6-12 days. You need to find enough hCG in the urine to get a positive pregnancy test, and with most current pregnancy test kits (sensitivity 25 milli-international units per milliliter) the pregnancy hormone hCG can be detected in the urine as early as 3-4 days after implantation (9-15 days after ovulation), though oftentimes it can take longer because the urine may be diluted or there is not enough hCG yet in the urine, or implantation happens later than extected. Our pregnancy calendar will help you calculate the due date and other important dates, and our ovulation calendar will calculate your fertile days.

Here are the expected positive positive home pregnancy tests in women who are pregnant based on a scientific study:

Expected Period (EP)

Pregnancy Test Positive?

  • About one in two HPTs are expected to be positive 2-3 days before a missed period
  • Three in four HPTs are expected to be positive on the day you miss your period

  • A negative pregnancy test on the day of a missed period is normal in about one in four pregnancies, and within the next 4-5 days most HPTs usually have become positive.

  • A negative HPT result 10+ days after the missed period makes a pregnancy unlikely.

    From: Wilcox in JAMA 2001; 286:1759

    Positive Blood Pregnancy test

    The blood pregnancy test is usually positive within 3-4 days after implantation or about 9-10 days after fertilization and ovulation. About 5-6 days before a missed period

    Positive Urine early home Pregnancy Test (HOME HPT)

    The early positive urine pregnancy test will become positive about 2-3 days after the positive blood test or about the time of a missed period, and sometimes a couple of days before the missed period. About 25% of pregnant women will test positive with the early home pregnancy test about 2 days before a missed period, and about 40% the day before the missed period.

    The wide variation of when the urine pregnancy test becomes positive and how early pregnancy can be detected are due to four variables which determine when the home urine pregnancy test becomes positive:

    1. Timing of Implantation

    A pregnancy test detects the presence of the pregnancy hormone hCG (human chorionic gonadotropin) either in the blood or in the urine only after implantation. Implantation can happen as early as six days and as late as 12 days after fertilization/ovulation. At the time of implantation the placenta starts making the pregnancy hormone hCG, which then enters the blood stream. How early pregnancy can be detected depends on the pregnancy hormone hcG which can be detected in the blood about three to four days after implantation. Urine hCG can be detected about two to three days after blood hCG can first be seen. Detection of hCG depends on timing of implantation, so hCG can normally be detected in the blood between nine and 16 days after ovulation (HPT: 12-19 days after ovulation).

    2. Blood hCG Level

    There is a wide normal variation of hCG levels, both in the blood and the urine and this wide range changes the diagnosis of how early can pregnancy be detected. If a woman has a normal but low blood hCG levels, then it can take several more days for it to show up on a pregnancy test.

    3. Urine hCG level

    Urine hCG levels change over the course of the day depending on how much you drink and how diluted or concentrated the urine is. Urine pregnancy testing is best done with more concentrated urine. So how early can pregnancy be detected depends on the urine concentration and the quality of the early pregnancy test. If you drink a lot of fluid, the urine may be too diluted early on in pregnancy to achieve an hCG concentration adequate enough for a positive test.

    4. Sensitivity of the Early Urine Home Pregnancy Test

    Different pregnancy tests have different sensitivities and that has an impact on how early can pregnancy be detected. The lower the sensitivity, the earlier a pregnancy test becomes positive. Sensitivities are indicated in mIU/mL, the lowest amount of hCG in the urine that tests positive. A sensitivity of 20 mIU/mL requires one-half the hCG level to be positive when compared with a 40 mIU/mL sensitivity level, and it may become positive several days earlier than the pregnancy test with a higher sensitivity. Make sure you read the package of the pregnancy test to determine your pregnancy test’s sensitivity.

    A positive pregnancy test occurs only after the fertilized egg has implanted into the uterus and sent enough hCG (i.e. the “pregnancy hormone”) into your blood stream. So the first positive pregnancy test does not usually happen until a couple of days prior to the next expected period. If it is truly positive then it’s highly likely that you are pregnant because false positive pregnancy tests rarely occur.

    CALCULATOR: When to take the pregnancy test

    After ovulation and fertilization the fertilized egg or blastocyst takes 4-5 days to travel through the Fallopian tube towards the uterus and it then usually implants inside the uterus. Implantation , when the fertilized egg the embryo implants into the endometrium, happens about 9 days after ovulation (range: 6-12 days), and it takes another 3-4 days after implantation (9-10 dpo: days after ovulation) for the blood pregnancy test to first become positive.

    • Blood Pregnancy Test: If you are pregnant then the blood pregnancy test is usually positive within 3-4 days after implantation or about 9-10 days after fertilization and ovulation.

    • Urine Home Pregnancy Test (HPT): The urine pregnancy test will usually not become positive in most women until a missed period or about a week after implantation. The urine test is usually positive at a missed period, but only about 25% of pregnant women will test positive with the HPT 2 days before a missed period, and about 40% the day before the missed period. On average, a pregnancy test will be positive 13-14 days after ovulation and fertilization, or about the time you expect your menstrual period.

    The amount of time it takes for a pregnancy to be detected and the wide variation of time it takes for a urine pregnancy test to become positive is due to five variables:

  • Timing of implantation

  • A woman’s weight (being overweight lowers the hCG)

  • Urine hCG level (e.g. how concentrated or diluted the urine is)

  • Sensitivity of the pregnancy test

    1. Timing/Day of Ovulation : A pregnancy test depends on the day of implantation and the urine pregnancy test is usually positive 4-5 days after implantation. However, the day of ovulation is important too, as implantation can only happen if ovulation took place and the egg was fertilized. Therefore, if your day of ovulation was later than you thought, implantation and subsequently the positive pregnancy test will also be delayed. This is why it is really important to keep track of your ovulation day (OD) so you can start counting the days to implantation and eventually the positive pregnancy test.

    2. Timing of Implantation: A pregnancy test detects the presence of the pregnancy hormone hCG (human chorionic gonadotropin) either in the blood or in the urine. The hCG in the urine comes from the hCG in the blood after being filtered through the kidney. After ovulation, the egg gets fertilized and travels through the fallopian tube toward the uterus. This journey takes about a week on average. Implantation, the attachment of the fertilized egg to the lining of the uterus, occurs on average about a week or so after ovulation/fertilization, but it can happen as early as six days and as late as 12 days after fertilization/ovulation. At the time of implantation, the placenta starts making the pregnancy hormone hCG, which then enters the blood stream. How early a pregnancy can be detected depends on the pregnancy hormone hcG, which can be detected in the blood about three to four days after implantation. Urine hCG can be detected about two to three days after the blood hCG can first be seen. Detection of hCG depends on timing of implantation, so hCG can normally be detected in the blood between nine and 16 days after ovulation (HPT: 12-19 days after ovulation).

    3. Blood hCG Level: There is a wide variation of “normal” hCG levels, both in the blood and the urine. This wide range changes the diagnosis of how early a pregnancy can be detected. If a woman has low blood hCG levels, for example, it can take several more days for it to show up on a pregnancy test. If a woman is overweight, with a high BMI, then the blood hCG levels are often lower.

    4. Urine hCG Level: Urine hCG levels change over the course of the day depending on how much you drink and how diluted or concentrated the urine is. The time it takes for a pregnancy to be detected depends on the urine concentration. If you drink a lot of fluid, the urine may be too diluted early to achieve an hCG concentration adequate enough for a positive test. Urine pregnancy testing is best done with more concentrated urine.

    5. Sensitivity of Urine Home Pregnancy Test: Different pregnancy tests have different sensitivities, which affects how soon a pregnancy can be detected. The lower the sensitivity, the earlier a pregnancy test becomes positive. Sensitivities are indicated in mIU/mL, the lowest amount of hCG in the urine that tests positive. A sensitivity of 20 mIU/mL requires one-half the amount of hCG to be positive as a test with a 40 mIU/mL sensitivity level; it may become positive several days earlier than the pregnancy test with a higher sensitivity. Make sure you read the package of the pregnancy test to determine your pregnancy test’s sensitivity.

    Spotting and positive pregnancy test

    Some bleeding early in pregnancy, maybe some drops or brown discharge, is also called ‘spotting.’ Spotting happens in 20-30% of pregnant women, usually around the time of the missed period, and most women with spotting continue and deliver a healthy baby. Implantation bleeding usually happens 5-6 days after ovulation. If your pregnancy test is positive, then implantation happened at least 4-5 days ago and it’s unlikely that the spotting represents implantation bleeding. If you have a positive HPT and you experience spotting with pain and cramping, you should contact your doctor right away. Your doctor can check the viability of your pregnancy by doing two hCG blood tests 48-72 hours apart. If the hCG levels more than double, then you have a viable pregnancy.
