Hi guys, I'm 18 and technically a virgin but last night I got a little carried away with a guy. I'm not on birth control and he didn't have on a condom. He didn't put it inside me but there was a lot of rubbing it up against my vagina and according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> (which might not be right cause I just started using it) I'm in my 22% fertile days. He didn't actually cum but I'm scared about precum. Should I take plan b or am I just being paranoid ? Also I'm on antibiotics and idk how that and plan b would affect each other. Please help me out, I've never done this before and i'm a bit scared.
