Hi-my boyfriend is only boyfriend i've ever had and I, the only girl he's ever dated. Neither of us have ever had sexual intercourse with each other or anyone else. However, we have fooled around some recently. When we were dry humping a few times, I believe he pre cumed. Both of us were fully clothed while his genitals on top of mine. I have always had a strange menstrual cycle and I can never really tell when i'm about to get my period until I experience cramps a few days before. I had my period approx. a month ago but I don't have my period now. What are my chances of being pregnant?
