Dry Precum/possible ovulation

ThIs Is going to be quick because I'm freaking out...me and my gf were messing around and she gave me a little oral (I DID NOT cum). We stopped, wiped everything off, washed hands and ate dinner. About and hour later she touched me again, so I fingered her a little bit. I'm just paranoid because their may have been a tiny amount of dry Precum on the hand I fingered her with (I don't think there was, considering I only really touch myself with my right, and I fingered her with my left, so it would have to have been tiny amount). The things that scare me are one... I went kinda deep... She is a virgin though... And she may have been ovulating. Im concerned she could be pregenantIf she was it was the very end of ovulation, if she wasn't she just got off of it... Just any help would be appreciated... And regarding the potential Precum, the last time I jacked off was the day before and I've pissed at least three times since then
