If you took a pregnancy test too early, you could have a false negative. There are seldom false positive's though.
Your results can be a false-negative or a false-positive.
A false negative indicates that a person may not have a disease that is being checked for or that the person may not be pregnant. Having a false positive would be the opposite showing that the person does have a disease or could be pregnant.
There are several things that can contribute to a negative pregnancy test even if you are pregnant. Some medications can give you a false negative, the timing of the test can affect the results. If you did not follow directions properly; if you let the test sit for too long the results may read negative after a while. It is important to read the results within the amount of time given on the instructions of that particular pregnancy test you bought
No it can not.
Usually different results from pregnancy tests come from using the test too early. Taking the test too soon will cause a test to read a false negative. Some HPT are more sensitive than others, they will read positive sooner than a less sensitive test. False negative results are very common from using the test too early, false positive is almost unheard of unless the test kit was damaged somehow. Always check the kit before using it, including the expiration date and follow directions.
no, it will not give false results ~pawsalmighty but if you are having a period it is extremely unlikely that you are pregnant. "englishangel"
No you can't be pregnant and still have your period. You can have a light bleed but not a period. As for the whole negative test thing, it could be a false negative.
it's common to get a false negative, even if you are pregnant. but typically, if it reads as positive, you are pregnant
If you are not taking hormone supplements then you are pregnant. You can get a false negative, you cannot get a false positives.
Some infections in the kidney can cause false positive dipstick test results but not false negative.
Though quite reliable they can sometimes give false results
This happened to me when I got pregnant with my third child. The first test was negative and the second positive. From what I understand, a pregnancy test can give a false negative but rarely gives a false positive.
