Hi Cath23!
You're right, conception is actually on the ovulation day. I should probably rephrase the question. What I really meant is how many days before ovulation day did you BD... They say sperm can live 3-5 days, while more common is 2-3 days. This is why I asked, if an act say 3 days before ovulation lead to pregnancy or not.
I am a little confused with your days! But just a note here, ovulation day is not 14 days after the first day of your period unless it's a 28 cycle. It's 14 days before your next expected period. For example, if someone's cycle is 32 days then ovulation will happen on day 18-19 of that cycle, 14 days before next af is due.
Enjoy your pregnancy
