I'm 33 Weeks Pregnant, & I Haven't Had Any Complications

I'm 33 weeks pregnant, & I haven't had any complications at all with my pregnancy. I was just wondering if this is normal or if I should be worried? My husband was going down on me & fingering me. But then he randomly pulled his finger out, & it was entirely white. Like it was covered in some white discharge, not clear white. Is this just hormones answering differently? Or can it be early labor? Should I be worried?
