could i possibly get pregnant? first, we were dry humping, fully clothed. then, after a week or so, we went swimming. he did not ejac there or anything. but he was really close to me, and hugging and all. still, in shorts and stuff. 13days later i got my period. what worries me is that some people claims that you could get your period while being pregnant. so, am i? (my period came the week i was expecting it, but not on the exact date. it came a bit early. like 1-2days early)
