Hi all, me and my fiancé have been planning to conceive. We had unprotected sex on Aug 9 but the Calendar states I begin fertile the 10-16. With the 15 being my ovulation day.  I read online that sperm can stay up to 5 days. Which be the 9-13. So my question is, is there a chance I can conceive from that date.

Me and my fiancé work Opposite hours of 12 hours and the 9 which was a Sunday was our day off together. This is our first time trying to work around ovulation and understanding how ovulation works.
