I had sex that other night. We started without a condom but then he put one on. Later that night I felt like my ovary was cramping. Are the worries in my head since we had just had sex and he didn't ejaculate inside me? ... but i guess there was a possibility of precum.

If that could somehow get me pregnant, would birth control pills stop it? I'm starting the pill come this next month, and I wanted to know if that would make it better or worse. thanks.

when is the earliest I can take a pregnancy test and it be accurate? and if i am pregnant, are there ways to get rid of it myself?
