Had unprotected sex with my bf few days after my period and it was during my low fertility time. he came outside and i took after sex pill the one containing levonorgestrel. is there any chance i could be pregnant?

Unlikely, but...: Emergency contraception pills can alter the menstrual for the cycle in which they were taken, and sometimes the next cycle too. One should be sure to check a home pregnancy test about 3 weeks after sex, because emergency contraception pills work most of the time, but not all the time. Also, be sure to start using a reliable form of birth control, so that one will NOT need emergency pills again.
