In the beginning of April I had unprotected sex. He didn t cum, but I was told Pre-Cum 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. Is this all in my head, or could I possibly be pregnant?
