Can pregnecy tests somehow give the wrong answer?

Answer 1

Yes; 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. If you did not perform the test properly (example: you drank a lot of fluids before taking the test, which can dilute your urine). Etc On rare occasions you can encounter a false positive due to improper testing, expired pregnancy tests, rare medical conditions such as certain types of cancer, evaporation lines, a recent pregnancy or a chemical pregnancy.
