Okay, me and my girlfriend was fooling around. She have started to get cervical mucus at 19 and we fooled around at 20. She gave me some blowjob and when my hand came close to my penis i felt some pre-cum get into the back of my hands and back of my fingers. but i'm very sure, nothing got into my middle finger or my palm.. After 3-5 minutes I started to finger her and before i insert it. I'm pretty sure that I wiped my hands in my pants, but I can't remember if I wiped the back of my hands. I'm really freaking out, because my mother said cervical mucus means that a girl is ovulating and the chance of getting pregnant is higher. But when i told her what happened she said that it's impossible. My girlfriend is also not worried. Is there a reason for me to get worried on this situation? My girlfriend is also virgin and we haven't had sex yet.
