Pregnant?

Kyna • I know a few things, but I'm no expert.
I'm supposed to get my period tomorrow, but I'm still afraid. Ive had sex every weekend for the last month. I'm on birth control and my boyfriend usually pulls out. I've been having diarrhea, and that could be an early sign of pregnancy, but I've also been eating a lot of plums lately. Maybe I'm just paranoid.
