My bf and i had sex the 29 of December (1 day before fertility window) with a condom and even then he didn’t cum inside me. Before that we had a quick round of unprotected sex Dec. 23 but i was on my period and he pulled out a while before he came (to try and eliminate the possibility of pre cum). The last day or two i have felt light cramps and muscle soreness around where i would usually get my period cramps. I have tried to do research on what signs to look out for pregnancy wise just to try and be safe. The cramps are giving me a little anxiety though..I’m 17 and my parents don’t know i have had sex. I’ve tired to get on the Pill for my painful periods but my parents won’t let me so condoms are my only option. I just don’t know much about contraception or how best to prevent it and need advice on how to best go about being sexually active because i lost my virginity last month.
