My boyfriend and I were 'hooking up' about 44 hours ago. There was a mix of oral sex for both of us and also hands. Towards the end he decided to jerk off because he hadn't come yet and ended up getting **** all over himself as well as my arm. So we had to clean up. At this point I was at the end of my period and wearing a tampon, I said we couldn't have sex because of this (also I'm not ready). I'd say 10-15 minutes later he fingered me, (there would have been the tiniest amount of *** on his fingers, if any). I'm 16 btw. What are the chances of me being pregnant, and should I consider plan B? (Also I'm on the pill for my skin but pretty bad with taking it so it wouldn't do much)
