So this happened and me and my gf are freaking out. My girlfriend sucked my penis and some cum definitely went inside her mouth. Then she sucked my finger for a while. Then I fingered her using the same finger.(i touched her clitoris). We're worried that the cum from her saliva could've entered her through my finger. Is there a chance of her getting pregnant? if so how big is it? and what can we do now to prevent it? (it's been 6 days) ps: she's still a virgin, we've never had sex before. Pps: I fingered her on an afternoon and on the same evening she got her periods.
