Ovulation following Two period in one month

I had my period twice in one month. Very irregular for me. However, I had unprotected sex the first day of my second ovulation. He said he pulled out but then he was worried that maybe he hadn’t in time. We had sex three times:/ Are the chances of me being pregnant high? Is my fertility the same if I menstruate twice in one month? Can I really ovulate twice in one month? I’m really confused and a bit worried.
