My boyfriend and I were messing around two days after my period and we were both wearing underwear. I was on top at one point and he asked me to get off, that he had gone off . When I lifted myself, there was a dime sized spot from him on my underwear, and a larger spot from me. He never went inside of me, but was only near the area....what are my chances of getting pregnant? Also, we don t plan on doing this again without protection, I m already worried about it enough....
