Could you be BE pregnant? Well, that would depend on how long ago it happened, since it takes a while to actually get pregnant. If it was within the last day or two, maybe you could get the morning after pill if you don't want to get pregnant.
Yes, you can get pg, with that risky behavior. Like the previous poster said, if it was in the last couple days, the morning after pill, would be a good choice. Also use birth control, everytime you have sex. If you went through these boards, their is a young girl on here, who got pg doing the same thing you are.
