I am facing an urgent and important medical situation that needs your advice.
Me and my boyfriend were dry humping. We had 4 layers of clothes between us (2 pairs of cotton underwear, polyester shorts and basketball shorts). We were gyrating, grinding and thrusting. At one point i could feel him at the entrance of my vagina, and filling it up. My underwear was wet at this point, and so was his. He assures me that he had ejaculated, but none of his fluid left his underwear. To be sure, I checked my shorts and there were no stains (semen stains or vaginal stains). However my underwear was stained with white patches.
What are the chances of me being pregnant?
