Ive been taking birth control pills for two weeks now, and i took my first pill a week before i was supposed to start my period. But now im two weeks late for my period.. I did get brown spotting for 2 days, but thats about it. Is it possible that im pregnant? Because 1 week before deciding on BCP, i had sex, but then i took plan b right away.. So yeah, please help :( im so worried
