"i was on birth control, however i decided to stop taking it on saturday, 9/5/15 because i thought it was causing my sinusitis. i got my period on the monday after and it lasted till friday. i had sex with my boyfriend on friday september 11th with a condom but it broke and he came completely inside me. i&#039;m assuming that my birthcontrol was still in affect because i was still ending my period of the placebo week, but just to be sure we  went to the shops  and bought generic brand plan b(levonorgestrel) and took it 40-60 minutes after. i started bleeding right after i took plan b but i assumed it was my period. i stopped bleeding that night but two days later i started spotting. currently having bad cramps and expecting my period sometime next week."
