I have irregular periods, I am currently late( on 56 cycle) so I did a pregnancy test. Pregnancy test which came out as positive. I then did another pregnancy test an hour later and it was negative. I have done numerous pregnancy test after and they've all came out negative, so now I'm wondering if the positive pregnancy test was a false positive or evaporation line? I did pee a bit on the test window which might be the reason why I got a positive result, is that possible?
