Likely hood????

Okay so over the past three days my boyfriend and I had sex five times. I've been on a pill for two weeks today (Sunday) but I'm just worried because the first day was the day I would have ovulated if it wasn't for the pill. He never finished inside of me he always pulled out but again on the first day we went for a round two and he hadn't gone to the bathroom before hand, which is a method that people who use the pullout method suggest so there's no sperm in the precum, it's just that we did it a lot but again he never came inside of me. I'm just worried about whether the pill will be effective or not especially because I didn't realize we were doing it when I would have been ovulating. Am I just being paronoid?
