False Pregnancy Test

Can you get negative urine pregnancy test results when you are pregnant?

Yes, you can get a negative urine pregnancy test result during the early stages of pregnancy, the home tests are not 100% accurate. To test for pregnancy, the urine tests determine the amount of hCG (human chorionic gonadotropin), the hormone of pregnancy, that is in your urine. But they are not very sensitive tests. If there is enough hCG that the test can work to detect it, then the result is a positive test (you are pregnant). In very early pregnancy, until the level of hCG rises high enough for the test to react and give a positive result, you could be pregnant but get a negative test.

It takes about 5-10 days for the fertilized egg to reach the uterine lining. Once it gets there, it implants and starts producing the pregnancy hormone. It can take a couple of days to show up on even more sensitive tests. Therefore, you could have conceived, but not implanted the ovum yet, which still gives a negative test even though could actually be pregnant.

Try taking the test in the morning. That is usually when your urine is most concentrated, making detection of the hCG easier. Wait another week and then recheck. If it still comes up negative, and you still think you might be pregnant, go to your doctor for more sensitive testing or continue to periodically test at home. If you get a subsequent positive test it is usually a good idea to follow with a second test to be sure you didn't have a false positive.

Some medications can give you a false negative, and, as mentioned above, the timing of the test can affect the results. If you did not follow directions properly (for example, if you let the test sit for too long the results may read negative after a while, or if you drink a lot of fluids before taking the test it can dilute your urine and give inaccurate results). It is important to read the results within the amount of time given on the instructions of that particular brand of pregnancy test.

To ensure the best results: Take the test in the morning, if possible, because your hCG (pregnancy hormone) levels are at it's highest, don't drink a lot of fluids before taking the test because it will dilute your urine and can affect the results Take the test no more than 1 day before expected period. Although some tests say that you can see results up to 5 days before your missed period, the percentage of accuracy is very low. Urinate for as long as possible on the foam-like strip. Check the results during the exact window of time suggested by the instructions of the pregnancy test.

A negative test could also be the result of a phantom pregnancy. A phantom pregnancy is where you basically fool your mind and body into thinking it is pregnant. You will still experience pregnancy symptoms but you are not actually pregnant; it is all psychological. Some women have even been able to lactate during a phantom pregnancy. The psychological causes of a phantom pregnancy are usually either paranoia of being pregnant or having an extreme desire to become pregnant.

There are alternative pregnancy tests that can be used in addition to using a home urine pregnancy test. You can go to your OB-GYN to get a proper examination and pregnancy test. They can order a blood test to be done at a lab, or perform one themselves in some cases. A pregnancy blood test can only be performed when ordered by your physician.

There are two types of blood tests to measure the level of hCG: Qualitative and Quantitative beta hcg blood test. The Qualitative blood test is not 100% accurate during the early stages of pregnancy, so it is best to have this test performed after 5 weeks into pregnancy for a more conclusive result. The Quantitative beta hcg pregnancy test is 100% accurate and can be performed as early as 5 days after intercourse. The results will usually take 3 days to come back from the lab and are very accurate and are the best way of determining if you have conceived.

Pregnancy - hCG Levels

What does your HCG level mean?

It doesn't tell you how far along you are, just that you are pregnant. HCG is the hormone women produce when they are pregnant. Here are more opinions and answers from other FAQ Farmers: * Your HCG levels double every 2-3 days during your pregnancy. * HCG (Human Chorionic Gonadotropin) is a hormone produced ONLY during pregnancy. Pregnancy tests screen for this by a urine test, it's there or it's not. * Contrary to Jamie's response, your HCG level can indicate roughly how far along you are in your pregnancy. Ask your doctor. * HCG is not only produced when pregnant. Males can have HCG levels high enough to be detected by a home pregnancy test and women can also, when they are NOT pregnant. The HCG can be produced by certain tumors. In pregnancy HCG keeps the corpus luteum around to produce estrogen and progesterone, which are necessary in pregnancy. Also, HCG levels differ from each pregnant woman and the doubling is the most important factor. A high HCG level can also indicate a multi gestation pregnancy

Pregnancy - hCG Levels

How long after a miscarriage will a pregnancy test still show positive?

It depends. I know this is likely not what someone who is hoping to be pregnant after a miscarriage wants to hear but there isn't a definitive answer since it depends when the miscarriage happened (how far along was the woman?) and also how long it takes for the hCG (the pregnancy hormone detected by pregnancy tests) to leave her system.

If a woman is wondering if a positive test is indicating the hormones left by a miscarriage or is a sign of a new pregnancy, she should go to her doctor or midwife for a quantitative (not qualitative) blood test or an ultrasound. A quantitative blood test will measure how much hCG is in her system while a qualitative blood test will do the same thing a urine test does -- say whether or not there is any hormone there. An ultrasound will examen the contents of the uterus to see if there is an embryonic sac or missed particles from the miscarriage.

What are HCG levels?

HGC LevelsHere are answers and opinions from FAQ Farmers:
  • I don't know the exact definition, but it is a hormone a woman's body produces when she is pregnant. Home pregnancy tests have chemicals that "look" for HCG in the urine. If there is HGC in the urine, the test will show a positive.
  • HCG stands for Human Chorionic Gonadotropin, a hormone ONLY produced during pregnancy. I'm not really sure if "levels" are important, just if it's there or not. That's what pregnancy tests screen for in your urine.
  • From what I understand, after two or more blood tests, the doctor can tell wheather the levels of HCG are rising, or lowering. If they are rising, it is good, because it rises a lot over the first three months (also the cause for most morning sickness). If they levels are rapidly decreasing, it's a sign of a miscarriage (that happened to me, that's the only reason I know all this), and if it's slowly decreasing, it probably means your into your second trimester, when the levels do drop or stop excessivly reproducing, but of course, still stay in your system. From one blood test, they can see if your pregnant, that's how the home pregnany tests work as well, but they can't tell if the pregnancy is viable until one or more blood tests are taken. I don't know if all this is totally right, but it's the gist of it.
  • The Human Chorionic Gonadotropin is a hormone produced by the mother's body during pregnancy. This is also the hormone for which a home pregnancy testing kit will test. Most home pregnancy tests will detect levels of HCG at or above 50mlU, but some 'early response' style tests can detect smaller amounts. In a normal pregnancy, the HCG levels should at least double every two to three days in the first trimester. This is why two blood tests taken a couple of days apart are often used to determine the viability of an early pregnancy.

------------------------------------------------------------------------------------------------------------

To be honest part of your answer is wrong. You can receive HGC after you are pregnant as well. If you look up on the internet about molar pregnancies... there is weird way that HGC levels are given off into your body without you being pregnant.

_____________________________________________________________________

Rising HCG levels during pregnancy is important. If not enough HCG amount to support the current state of pregnancy the baby may be miscarried. Urine samples are done at every dr. appt. to check to make sure you have the right levels etc...

If my blood HCG level is 7.5 does that mean I am pregnant?

You cannot have HCG in your system unless you are pregnant or have recently been pregnant. As pregnancy week numbers are counted from your last period and not from the day you actually concieved, a figure of 7.5 would imply you are 4 weeks pregnant, ie that you concieved 2 weeks ago. The level of hcg in your system should roughly double every 48 hours if you are experiencing a normal pregnancy. If the hcg levels drop it is likely you have suffered an early miscarriage.

Actually you CAN have HCG in your blood without being pregnant. Any level ABOVER 25 means you ARE, since your levels are 7.5, more than likely YOU ARE NOT!

The Difference Between

How can you tell the difference between a miscarriage and a period?

A lot of women track their flow and if you are pregnant and you experience abnormal amount of blood, blood clots big or small, painful cramps it's a good chance that you are having a miscarriage. First off you need to know if you are pregnant or not, if you are and you are having any of those miscarriage symptoms I named off please see your doctor immediately and if necessary go to the emergency room. If you know you are not pregnant and use birth control and experience some heavier than usual blood flow, know it could be a diet change, stress, and much more. I recommend taking some vitamin C pills daily because not only does it help keep the cold away but it can also reduce heavy menstrual bleeding.

What would cause bleeding and a rise in hcg levels a week after a miscarriage?

You do need to see a doctor about this to see if you may still be pregnant. Babies can survive quite a lot of bleeding and there are many documented cases of them or a twin escaping even a D&C.

The other possibility is that you had a hydatidiform mole which is a condition where nothing develops properly, but makes cancerous-type growths which can spread if left untreated. This is uncommon, but either way, you should see a doctor.

If breasts stop hurting at the end of the seventh week is it possible you have lost your baby?

Just because your breasts stop hurting at seven weeks doesn't mean you lost your baby. It just means that you maybe one of the lucky ones. Some women never have pregnancy symptoms to even comfirm that they are pregnant. No what it means is that everyone's body reacts differently to how they are doing in their own pregnancy. Are you still having other pregnancy symptoms or have they stopped to, this is very important? Hopefuly it is just the sore breasts that have gone away, if you get a chance check back with me, i'd be curious to keep talking with you. Do you have other symptoms or is that the only one? From the Questioner: I was worried for a day or two, but now it's apparent everything is okay -- I still have LOTS of other symptoms. I had a "missed abortion" last time round, so I guess I was really expecting no better this time. Most of the books say breast tenderness might change about end of first trimester, I only found one tiny reference that suggested they MIGHT feel a little better by the third month.

Could your HCG level go up because of what you eat or something else if you are not pregnant?

HCG IS not related to dietary intake. Certain fertility drugs could cause hcg levels to rise.

HCG will not ever be detected if you are not pregnant. HCG is a hormone produced by pregnancy and has nothing to do with anything you eat.

HCG can be produced if you have some cancers or ovarian cysts.

When is a woman's fertile period?

The fertile peak is at ovulation and up to a week beforehand when there is fertile cervical mucus.

Typically ovulation will occur two weeks before menstruation, with a viable egg being present for up to 48 hours, and a woman will produce fertile quality cervical mucus for up to a week beforehand - she can get pregnant as a result of sex during this time. During the average 28 day cycle this would mean a woman would be fertile between days 7-16, but obviously not everyone's cycles are 28 days and cycles can change all the time. Unless using Fertility Awareness Method you can't know for sure when a woman is fertile or not, thus if wishing to avoid pregnancy assume she is always fertile.
