Re: Question about mucus plug..
I lost my plug TWO WEEKS before I had my middle ds. I hope you don't have to wait that long, lol! From the other side (hospital side, that is), don't rush to the hospital and tell them, and please don't bring it with you! Just joking, most women don't do this, and I can kind of understand why, everything freaked me out when I was pregnant and it got a lot worse, not better, when I became a RN.
Usually, losing the plug is a good sign that labor is near, maybe not too near, maybe days, or even weeks before labor begins, but I have found most usually labor starts withing 1-7 days after loss of the plug. Lossing the plug means your early contractions are doing the job and dilating your cervix a bit, in prep for labor. Good luck, and hope you start labor soon!
