i had sex with this guy but it lasted like 30 seconds or less because he came so fast. we didn't use a condom he used the pull out method. i saw his cum all over his bed. before that i had given him a bj and he ejaculated and used a towel to clean himself. i gave him another half bj before he put it in. this occured 4-5 days before my projected period. i have an irregular cycle but I've always gotten my period i can't remember ever missing it. it's now been 3-4 days since my projected period and a week since i was with him. i know stress can delay it or whatnot this past month I've been more stressed and i got a job and the week i was suppose to get my period i got sick could any medicine have an affect on my period ? i spotted twice though when i cleaned myself after peeing and it was a brownish color. is there any way i could be pregnant ? im worried
