I have had a cold for a few days now with some pretty hard coughing. I have some
sore abdominal
muscles but seem to be on the mend (I hope!). After coughing at times, I have had some small amounts of stringy mucus (sometimes like egg whites). 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.
