Hi. I had unprotected sex a week ago, but none of us was wet, so he couldn t get completely inside me, cause it hurt. He didn t cum, as i said, he wasn t wet at all. This was all a week before my period was supposed to start. So, today, exactly a week later, i got my period, i think. It s watery and dark brown, and it had never happened to me. My breasts are sore, but they were even before we had sex. I ve experienced a liiiiittle nausea, but I m blaming it on the hot climate. Is there a chance I might be pregnant?
