Peeing does not get rid of sperm
And also for the main post pre ejaculation isn't based on how much you pee..
Are you kidding me.. your not pregnant if you get your period maybe you should do some research or go to a sex ed class.
Me and my bf we had an unprotected sex on Thursday and he ejaculated in me,then on Sunday I started menstruating.so is there any chances for me to fall pregnant?I really need a baby
I guess there is always a possibility, but in this case i'd say it's very unlikely. If your concerned about getting pregnant, try and get on birth control.
