Im 30 weeks and 2 days, and today as i was doing my makeup, and hair. I had sweats on no undies, well i walk into the living room to check on the kids and walk back and notice the inside of my legs were wet? I got some toilet paper, and it was like mucus... Like light pale greenish/yellow to a clearish white lol not exactly sure how to put it. But that was it no more after i wiped. There was some on the toilet paper but not a whole bunch. Could it be my mucus plug this early?
