Pre cum...

So my bf and I had sex today with a condom and I’m on bc and then about 30 minutes later we did it again (I don’t think he peed after). Right before we did it again I gave him a handy and may have gotten some pre cum on my fingers but I can’t remember and shortly after that I touched lube and put it on me (not in me but maybe near vaginal hole). What are the odds of me getting pregnant?? I’m 10 days away from my period??
