Lol @ Seesaw and CH! Just trying to help
I missed my period and that's why I knew, despite being on the pill, because I was always regular as clockwork.
I took the tests for the entire 6 months! Mostly to prove a point.
I was obviously showing already and still my tests were negative, but apparently I'm not an alien, only bloods and ultrasounds are to be trusted in our family, also oral contraceptives don't work on us. Obviously. My sisters had similar issues as well.
OP, I really didn't mean to scare you, just sharing my experience, I doubt you're preggerz tho.
