hi guys, so this is the case, my gf BJ me and i cum on my belly, and then she touched it a bit (and i kindda forgot if she did coz it was hard to trace it back) and then she scratched her vagina with a little bit of sperm. she then washed it in the bathroom, she is scared that the water that help wash the sperm can help it swim. she told me that she didnt even go inside it when she scratched her vagina. im scared if she is pregnant. but i strongly believe she is not, i need some advices please. she said she also had stomach cramps and boobs hurt on the clevege nothing else (2 weeks after the incident). she has a weird period that goes after every 3 months. please help guys

thanks, appreciate your opinions
