about 3 or 4 weeks ago my boyfriend at the time and i were fooling around and he ejaculated on my hand. i made sure to wash my hand thoroughly but there is a possibility that some precum got on my stomach. i was wearing jeans and underwear because at the time i was on my period. i was just wondering what you thought my chances of pregnancy were (as i’m a worrier and have gone as far as to look up abortion clinics) =/
