i took mylan for 2 months and missed both periods during sugar pill week, so i freaked out and decided to take a break instead of starting my 3rd month. the month where i would’ve been taking month 3 of birth control is almost finished and i STILL haven’t gotten a period. i had unprotected sex all the time leading up to taking birth control with only pull out for contraception, and this pretty much continued after i started taking mylan. i took one pregnancy test about two weeks ago and it came back negative. could it be a false negative? or maybe there’s something wrong with my health? should i be worried?
