scared I could be pregnant!! 😩

I just had sex with my boyfriend earlier today. I'm not on any form of birth control but we did use a condom. Well, we gave each other oral sex and we all know pre cum happens. When I gave him oral, pre cum was on my hands and then I rubbed my (you know what) with the same hand pre cum was on!! Is there any chance I could become pregnant? If so, what would be the percentage of me getting pregnant? I also am on Day 10 of my cycle
