What are the chances

What are the chances I get pregnant? I’m on the pill and I never miss taking it on time. Because I don’t trust it completely, we use condoms and my boyfriend will pull out before coming. Am I gonna be okay? Also, my period ended last Friday and I started my new pack today. Last week I was on the placebo pills. I’ve been taking my pills perfectly for 10 months now. Am I good to have sex tonight? Also, if I were going to ovulate (slim chance) would it be around the same time that I would ovulate if I weren’t on the pill?
