Maybe someone can help me then I had a similar thing happen when I was about 37wks and 3days. It was like a big gob of mucus about a 50cent piece but was slightly yellow. Was that my mucus plug or just discharge? I asked the doc and she said it could be a build up of discharge. I am due today and am having little cramps here and there but nothing to run to the hospital for. I never had this with my son, but he was 2 and 1/2 weeks early so all of this is new to me. HELP I'M GOING OUT OF MY MIND WITH WILLING THIS BABY TO COME.
