Taking pill perfectly. Can precum make me pregnant?

Jess

I've been on the pill for almost 7 years. I'm on a pretty high dose. I'm very attentive and consistent in taking my pill every day on time. My partner always pulls out before he cums, and then does so on me and not near that particular area. When I recently had sex with my partner, I felt something warm in me suddenly, not huge but noticeable. I asked if he had cummed, but he told me no. We've known each other all our lives so I believe him. And he proved it shortly after I asked. So can precum make me pregnant if I take the pill with nearly flawless use? I have to say nearly because I'm not a perfect human being, but I come pretty damn close when it comes to taking my pill.
