Okay, so I just had my period about 4 days ago. I'm on cycle day 10 now according to glow. My boyfriend and I were messing around just a little bit ago, he usually cums in my chest but today he messed up, ended up cumming a little on the top of my vagina (like where pubs are) I had underwear on, which which caught some of it -we took off &  cleaned up with soap &  water right away. I'm going to shower are soon as I get up but now I'm worried. My next period is supposed to be on the 19th. How worried should I be? What should I do? I don't think anything got inside or even near really but.
