A few days ago my bf and I were fooling around and I decided to give him a handjob for the first time. He had boxers and I had cotton shorts with lacey underwear. When he came, his boxers were wet, and I went to the bathroom to wash my hands. When I did this though I noticed the upper part(by waistband) was a little wet. Could I be pregnant? I started my period later that day but am really worried.
