I Have A Question. What Is The Probability Of Getting

I have a question. What is the probability of getting pregnant without intercourse? About a week ago I was fooling around with my boyfriend and I gave him a blowjob and a handjob. No cum touched our hands, only precum touched mine, but we washed them nevertheless with water and soap. About 15 minutes later he fingered me. I'm on birth control (zoely pills) for health issues, but I'm late and I'm starting to freak out. Is there a possibility of pregnancy?
