Hi everyone! Ladies, has anyone had this — all day a light dragging/ache like with your period, not very painful? Are these contractions or false ones? I'm 39 weeks, almost 40. It started at 4 a.m., I felt pulls at times, fell asleep by 6, woke up occasionally with a slight pulling in my belly that didn't really cause discomfort, and throughout the day I've had these sensations from time to time. What is it, has anyone experienced this? :)
