Condom Broke

My S/O & I were having sex on NYE. I am on birth control, we wear condoms EVERY TIME, & he pulls out prior to finishing. When he pulled out right before he finished, we found out the condom had ripped. He said that he knows for sure he pulled out in time, meaning he pulled out before he even started to finish, (which he did because he pulled out & then finished, I could see it) but I just wanted to see what everyone else thought. I think I’m fine, I take my birth control correctly (if I’m ever late taking it, it’s by like an hour, I’ve never missed a day or gone longer than an hour passed the scheduled time) but I’m just paranoid is all. Let me know what you think please!
