Pull out method during ovulation.

I had sex three times during ovulation. No protection. We’d go at it. Stop. Then again. So on so forth. Three different occasions. I’m not actively getting pregnant but we aren’t doing anything to not get pregnant. We are a “if it happens it happens.” However he pulled out each time. Three days till AF and I don’t feel like I usually feel when she’s supposed to come. What’s the chances of pregnancy? Some say you can’t get pregnant with pull out, and others say you can.
