well, i'm not sexually active, but me and my boyfriend have gotten close. in october during my ovualtion time he rubbed his penis against my vagina. i was completely freaked out afterward after learning that it's my ovulation time. my period came on november 14th. now it's december 17 and it hasn't came yet. my period is really sort of regular. i'm only 14 and i'm scared. there's a brown discharge right now. i don't want to be pregnant. help!! :-(
