I was hawing sex with my boyfriend, we used a condom, but when he was about to finish he pull it out and took the condom off and finished on my belly and a little on the top of my v mountain. I kept my hand there so nothing could get in but then I went to take a shower and after i cleaned with water I stuck a finger inside to clean there too. Is there any any chance some sperm got in and I could have gotten pregnant from it? I know there are slim chances but this worries me.
