Confused, Worried, Looking For Second Opinions

Okay, so let me explain. About a week and a half ago me and my bf had sex. We used a condom and I was on BC, I didn't feel him cum in me (cuz supposedly you feel that.?). Over the past week I've been not keeping up the greatest with taking my BC because my life has been flipped upside down. I'm now staying with my aunt.. so I'm wondering if I sinked with the ladies here? Could I be prego? I have signs of period but a lot of prego signs and period signs are the same...
