hi I have a question. so my boyfriend and I are trying to have a baby. I had my last period on august 16th and ended the 22nd. my ovulation day was the 30th of august. and my boyfriend and I had sex 3-4 days before my ovulation day and ejaculated in my all of those days, and too add he ejaculated in me the day before my ovulation day. and I checked my ovulation calander and it says I'm suppose to start my period the 13th of this month, which I obviously don't want to and I'm hoping I don't. but what are the chances of me getting pregnant?
