I had an intense session of dry humping a couple of days ago and he claims that he came but his pants were not wet at all, however as far as I remember I did feel wet but that could either be as I was aroused or was sweat, I also had my periods got 3-4 days after that but they did not seem like normal periods. After my periods I have a constant dull ache in my pelvis and my breast feel sore, I can feel my vagina also constantly wet since last 2-3 days. I'm worried if there are any chances of pregnancy. What should I do, please advise.
