I had unprotected sex with my ex boyfriend last week a couple of times. I dont know what the signs of pregnancy are, but it hasnt even been 2 weeks since I last had unprotected sex. Right now, I feel naseous, my stomach is hurting, no back problems, I've been using the bathroom alot these past few days. The thing is I dont think he came in me. I know he pre-came inside, but I'm not sure he pulled out in time cuz when he pulled out, it was dry. Plrase help me!! I'm only 20 and I dont know what to do....
