Supposed to be ovulating.

Has anyone had sex the day you finished your period or day after and gotten pregnant and found out during your glow “ovulation” dates? It’s been 15 days since I had sex after my period and I’ve took 3 naps today, slept the whole 6 hours from the beach to home yesterday, and have been moody as I’ll get out. And very emotional and sensitive. I don’t know if it’s possible or how likely it is.
