Hi, we were dry humping and My boyfriend ejaculated in his underwear. I was fully clothed but my skirt was up and our underwear was touching. 2 minutes later I wiped myself just in case and he says it didn't touch me at all. And 4 days later, I got my period on the expected day. I also took 2 tests 16 days after and they were negative. I'm paranoid cause I have breast tenderness but its 12 days before my next period. And I have a sinus cold so I'm thinking it could just be fatigue. Do I need to be worried?
