Possibly Cum?

This probably is a stupid question but I’m sort of new so...🤷‍♀️

I was masturbating and really close to having a orgasm but stopped because something startled me out of my zone and lost the feeling. But when while I stopped for just a moment, I felt something kind of leak I guess from down there and when I looked at my fingers I saw a bit of white stuff on them, and was wondering if that could possibly be cum? I’ve never had a orgasm before so I’m not really sure what that was and if possibly need to go to a doctor or something...😅
