My cervix is very low and hard. I have discharge that feels like my period. I have sex twice on November 5th and 8th ....3 weeks after my last period. Every time we used a spermicide condom, im pretty sure i wasnt fertile, he pulled out, he also finished before we had sex and he peed. Im super scared and i dont have anyone to talk to about this.My boyfriend doesnt thknk i am, and im also big for my age. I dont have any sore boobs or back pains but im so scared.
