My period started July 14th. Ended the 20th. My Hubby and I had sex Wed. night and Thurs. morning. That would mean my most fertile days are the 24th and the 28th.
I hear sperm lives inside for up to 7 days. Is it possible I could get pregnant?? I HOPE SO!
He moved to FL Thursday, for a new job, so I have to wait until Aug. when I move down there after school is done.

Could I become pregnant??

Considering that your period ended 3 days ago, it's unlikely you will get pregnant. Yes, sperm can live in the vaginal canal, uterus and fallopian tubes for as long as 5-7 days, but toward the end of their life-span they get "tired" and less likely to fertilize the egg.

You must also remember it takes the average healthy couple up to a year or more of actively trying before actually conceiving.
