Well, during week 2 of my birth control pack (yaz) i missed two days because i was horribly sick. I then started to bleed. I know that missing pills causes this its just really weird because even after i take my last "active" pill its a good 4 or 5 days until i start my actual period. Anyways, its been a week and ive been taking my pill on time but yesterday i did have sex and now im worried that the pill wasn't working? So, did just missing 2 pills make it not work? the bleeding stopped a few dais ago. Obviously i know that i can get pregnant anytime on the pill but i also know it takes 7 days to work after youve missed so idk.
