I am 38 weeks pregnant (almost there!) and have just started to notice little popping sounds coming from down near my pelvis area. My midwife has never heard of this before ... Has anyone else experienced it or know what it means? I'm not really worried; just curious; it doesn't hurt. It seems to happen when the baby moves - and may be my bones shifting a bit. At first I thought it might be my waters breaking, but it's not. Any ideas gratefully received!
