So me and my boyfriend had oral sex and he ejaculated just a tiny bit on my face. I wiped my face off with my hand and then waited a little bit (around 2 minutes, but the sperm wasn't completely dry). I touched my vagina with that hand but then I wiped off immediately once I realised I had sperm on that hand (I wiped my vagina off). I wasn't ovulating by that time (it was the first day after my period). Now my period is supposed to come in about 2 weeks but I started noticing breast pain and some short stomacn cramps. Could that be pms? Please help!
