dumb question...

okay so i’m still new to learning about sexual things but like i’m not having sex at the moment because i want to wait until i can have a prescription to birth control so i can be totally safe buttttt i wanted to know if there is a possibility if you get fingered and there is a little bit of sperm on your mans finger if that could get you preggo?? i’m still learning a lot so please don’t bash out on me i’m just asking to make sure
