Tonight, I had a very small clump in my underwear, tinged slight yellow. Can coughing cause preterm labor
or dislodge the mucus plug? I have had three children, all full-term, no problems with preterm labor. I think that I have had this mucus mixed with leukorrhea much of the pregnancy but can't remember! Could it be just the increased mucus production (like in my sinuses too)? I called my doc yesterday (this was before the clump in my underwear), and he didn't seem worried.
