My girlfriend and I had sexual activities today and we engaged in grinding where our genitals made contact. In the heat of the moment, we attempted to have vaginal intercourse but I think there may only have been actual penetration once but we stopped after that. I made sure to wipe away any of the pre-cum before penetration and there was no ejaculation. She mentioned that she had her period around the 2nd and this happened on the 12th. Is there a high possibility of her getting pregnant? I m not sure if it s relevant but I came once two hours before but I peed and washed myself after.
