Clear watery discharge after period is a sign of pregnancy?

31 weeks, has anyone experienced clear watery discharge, no odor, no pain. Kinda feels like a period gush at times like when I stand from laying or sitting. I hear it’s normal towards the 3rd trimester, then I hear of Premature rupture of membranes so a little concerned. Already contacted my OB, waiting on a response. Just curious if anyone else has?

I have a little of clear like jelly mucus discharge coming out. I even have spots of light pink on my panty liner. Been having contractions today. 30 weeks 2 days. Is this sign normal until I give birth?
