It's actually better to have sex before ovulation day, that way you ensure sperm is waiting for the egg to be released. I actually got pregnant with my girl having only had sex two days before I ovulated. We couldn't have sex the day before or the day of ovulation because of a busy schedule, but it worked out! So even if you missed ovulation day, having sex he days leading up to it still gives you a decent chance for this month.

Yes! The days leading up to ovulation , u are very fertile also. And can get pregnant on those days. Sperm can live inside your body for up to 5 days, under certain conditions like right ph level, and such.
