i have been taking birth control for over a month now, i'm in the middle of my second pack. friday i had unprotected sex and he came inside of me twice. Saturday i saw spotting but i figured it was from having rough sex. today, Sunday, i had the flow of a period. now i'm really nervous. health services at my college is closed today and my dr office is also closed. i didn't know where else to turn. i don't understand how i could have my period 2 weeks before i should while on birth control.... now i'm super nervous that i could be pregnant. had i known i would be getting my period this weekend i would have never had sex. what is the probability that this could actually be my period or could i have gotten an std? i got tested about a month ago and he said he was tested two weeks ago. if anyone has any information for me that would be greatly appreciated. health services doesn't open until 8.30 tomorrow morning and i would really like to know what's going on right now.
