So I have issues

I’m going to see my boyfriend this weekend and I haven’t seen him in a week and a half. I haven’t been sexually active all that long, but it never fails that I’m always scared I’m going to get pregnant. I’m on the pill and I take it perfectly. We use condoms and he pulls out before finishing. I know that the only 100% way to prevent pregnancy is abstinence. I had sex with him the last time I saw him which was also the last day of my period. Earlier this week I started spotting for just a little bit and it scared me that it could be implantation bleeding. But even so, my app says that today would be the day I ovulated if my pill fails. I want to have sex with my boyfriend this weekend but I’m really scared to get pregnant and would almost rather not. I don’t know how to talk to him about it. Should I not have sex or would you all say that I’m protected?
