Confused

Okay so me and my boyfriend have had a LOT of unprotected sex since July 31st. We had sex multiple times on my ovulation day and almost every day during that whole week leading up to ovulation and the 2 days after. My period was supposed to start on the 22nd of August but it didn’t. I started spotting on the 23rd a little bit and then the night of the 24th, I started bleeding. It was heavy. I had sex with my boyfriend and then my period literally stopped. Could I be pregnant? Or what’s going on? I’m very confused.
