Can you get pregnant if your boyfriend had precum on his fingers?

Basically me and my boyfriend were you know having fun and he was fingering me then afterwards we panicked bc he said he might’ve had some precum on his fingers. Now I’m worried that I might get pregnant and I don’t really know what to do. I know precum doesn’t have much sperm and he doesn’t know if he even had any on his fingers but yeah lol. Would appreciate any help? Like what are the chances of getting pregnant? I’m lowkey overthinking it ahha. Also I’m ovulating atm.
