Why do some women get a positive pregnancy test before others?
It’s rare – but possible – to get a positive result when you aren’t pregnant. This can be caused by very early pregnancy loss, an ectopic or molar pregnancy, fertility drugs, rare medical conditions, using an expired test, or even menopause.
Does a positive pregnancy test definitely mean you’re pregnant?
A positive result—even a faint line—on a pregnancy test means you’re almost certainly pregnant. False positive results are incredibly rare, and only happen if you have recently been pregnant, you’re on fertility medications containing hCG, or you have a rare medical condition that causes hCG to be present.
Why would I get a positive pregnancy test and then a negative?
The hook effect happens when you have too much hCG in your blood or urine. How is this possible? Well, the high levels of hCG overwhelm the pregnancy test and it doesn’t bond with them correctly or at all. Rather than two lines saying positive, you get one line that incorrectly says negative.
Can a digital pregnancy test change from negative to positive?
Evaporation lines happen when the urine that was on the test area starts to dry. The chemical composition of the urine sample changes due to evaporation. As a result, the test may start to display a positive line. After the allotted time has passed, you should discard the pregnancy test to avoid confusion.

What causes false pregnancy test?
It’s possible to have a positive pregnancy test even if you aren’t technically pregnant. This is called a false positive. It’s sometimes caused by a chemical pregnancy. A chemical pregnancy occurs if a fertilized egg, known as the embryo, is unable to implant, or grow, very early on.
