Hi, I haven't had sex. But, I did masturbate my boyfriend during the last day of my last period. Once he ejaculated I cleaned my hands with a towel and headed home. When I got home I went to the bathroom but I forgot to wash my hands before wipings my genitals with toilet paper. Is there any chance of getting pregnant? I'm on day 29 of my cycle and I still haven't gotten my period. I usually get my period on day 28-29 during the mornings. But, last month I got it on day 25. Could this be affecting my period?
