I am 38w 3d pregnant, and today I lost my mucus plug. Shortly after, I began to notice some mild cramping that has been going on now for about 4 hours or so. It's just constant cramping...not contractions. At my last doc appointment, I was 2.5cm dilated and over 80% effaced. Is it possible that cramping is an early sign? Did anyone else have this before they went into labor? Here's hoping!!!
