Am I Pregnant If My Positive Pregnancy Test Turned Negative The Next Day?

For many women, gathering up the courage to take a home pregnancy test is one of the most stressful experiences ever. The waiting period, particularly for women who want to fall pregnant, can be some of the longest minutes in her life. There is nothing more devastating than to take a test one day and have a positive result only to take a second test the following day and get a negative result. Since home pregnancy tests are 97% accurate, the question about whether or not the individual is in fact pregnant is a valid one.

Chemical Pregnancies and Early Miscarriages

One of the most common reasons for a positive result one day followed by a negative result the following day is due to a chemical pregnancy, which is commonly known as an early miscarriage. According to Baby Centre, early miscarriages are miscarriages that occur within the first trimester of pregnancy and is predicted that as many as 25% of all pregnancies end in a miscarriage. Early miscarriages are an extremely common occurrence and may explain why historically, there has been a tradition of not announcing a pending birth until after the first trimester. The signs of an early miscarriage are simply heavier periods and some women can go through their cycle without a clue that they have miscarried.

Overly Sensitive Pregnancy Tests

Home pregnancy tests work by testing a woman’s Human Chorionic Gonadotropin or hCG levels. This hormone is one of the first to increase during pregnancy. Many women who have been trying to get pregnant for a long period of time have access to high end technology and testing methods which are able to pick up the slightest increase in the level of the hormone. If you are testing shortly after conception, the level of hcg in your system will be very low. Testing at different times of the day or drinking too much liquid before testing can product a negative pregnancy test result when the hCG levels are extremely low.

False Negative Pregnancy Test

Another reason why the second test may have a negative result is that the home pregnancy tests may have been faulty and not worked properly. While this is not typically the case, it can occur on rare occasions. Instead of taking a pregnancy test as soon as possible, it is better to wait until your cycle has run its course. Waiting until a period has been missed is much more accurate than taking a pregnancy test shortly after conception.

    I went to the health department yesterday and took a pregnancy test. I did not take and HPTs. When I went in I peed in a dixie cup and waited for 5 minutes before the nurse came back in (with urine in my hand the whole time). When she came back in she took my urine and put it on the pregnancy test. The test appeared to be positive (with a faint positive line) then the positive line disappeared after approximently 4 minutes so the docotrs concluded that I am not pregnant. Are the doctors right? and Why did the test change to negative

    Unfortunately, if you keep testing and it continues to show a negative result, you could have had an early miscarriage. It could also be that you are just testing very early on in the pregnancy and the concentration of hcg in the urine can vary up and down. Depending on the sensitivity of the test, that variation may trigger a positive result or not.

    Hi can anyone help me please I am nearly a month late on my periods ive tooken a test a few weeks ago and I came back negative now I took one earlier on and it was postive for a while I felt really faint when I found out must of been a shock but then the test changed then to negative I do get a lot of the symptoms people have especially the one where I feel there something heavy starting to press in the bottom of my belly does anyone think I could be pregnant?? And when do you think I should do another test again???

  • Vickie B.

    It can’t hurt to test again now if your period is month late. If it comes back negative, maybe you need to go and see a doctor to find out what is going on.
