In the beginning of April I had unprotected sex. He didn't ***, but I was told Pre-*** can possibly get you pregnant. Well, I had sex 2 days before my period, multiple times. And had shower sex on my period. I'm having a lot of different symptoms. Including; Back pain, tightness in my stomach, heartburn, nausea, slight dizziness, cravings for everything. Could I possibly be pregnant or is this all in my head?
