Me and my boyfriend had sex today, he did most likely came inside me the first time and then the second time he pulled out but we believe he still came inside me a little bit. Right now I'm just 1 day before my fertile window starts. And I'm at 7.6% chance of pregnacy. Since he came inside me and in so close to my fertile window and ovulation, does that mean i might end up pregnant; probably? And estimate I heard sperm lives between 3 days to 7, if so I might end up pregnant? Cause we are trying to conceive.
