Not to turn any stomachs or anything, I am currently 31 weeks pregnant and I keep losing BIG pieces of my mucous plug(Mp). Had a check up at the beginning of week and I'm no longer dilated...I was at a centimeter. I'm having between two and four contractions an hour but my ob/gun says its nothing to worry about...but I'm nervous. P.S. contractions have been coming this way for around three weeks now. Is this a reason to worry???? 3rd pregnancy, 3rd baby
