Sex hours before your period .

Totiona • I'm 24, Mother to a beautiful little girl and a gorgeous little boy!!
Okay, so I had sex the 19th and the day of my period which was the 21st. It was unprotected and he came in me. I got off my period on the 25th. The 27th, 28th, and 29th we had unprotected sex as well. My fertile window Is the 30th-6th. The 4th being my highest percentage to get pregnant . My question is, with me having sex on the day of my period, hours before, could I still get pregnant?
