HELP!! I don't know?!

Saturday my boyfriend and I we didn't have sex but we were having some fun, and so we started making out and he started to insert his fingers and then I helped him out by jerking him off and when he cums I licked the cum off...but when I got home I went to the bathroom and washed my hands...I was still in the mood and so I decided to go rub my clit and I don't know if still had sperm on my fingers or not...so I don't know if I'm pregnant or not! I'm freaking out!!!  Help me!
