???

i dont know if this is the right forum for this question, but here i go. I havent had sex in a while, and the other day i did. but even a few days after the walls of my vagina are still puffy/swollen, they dont hurt or anyting. i already have a child and when i was pregnant that is what happened, but it was constant. we used protection and all, but i was wondering if it was just because i am not used to it anymore and because of the force. i dont want to get too worked up, but i worry that it is a possibility that i may have become pregnant again and i dont want that.
