Is there anything that can make a pregnancy test positive?
This is known as a false-positive. A false-positive might happen if you had a pregnancy loss soon after the fertilized egg attached to your uterine lining (biochemical pregnancy) or you take a pregnancy test too soon after taking a fertility drug that contains HCG .
What drinks can mess up a pregnancy test?
Yes! Drinking too much water — or any liquid — can affect a pregnancy test. The hormone hCG is more concentrated in your urine first thing in the morning.
What triggers false positive pregnancy test?
A test will only show a false positive if you have hCG in your system for another reason such as you were recently pregnant, are taking fertility medications containing hCG, or if you have a medical condition, like some rare ovarian cysts.
