Bc pill and withdrawal?

Hi all. I’m on birth control, the pill called Junel-Fe 1/20 which is a combination birth control pill. I’ve been on it for over a year and I am now in a long term relationship with my boyfriend. I take my birth control every day at 1:00 but sometimes I am a few hours late but I have never gone a day without taking my pill.

My boyfriend and I have sex pretty much every day and we don’t use a condom. However, he pulls out and never finishes in me. But of course I am a little nervous about pre-cum but I know there is a chance of pregnancy anytime sex occurs. This is my first serious relationship and not using condoms so if anyone has any advice I would really appreciate it! Thanks!
