I am currently 30 weeks 2 days. I have been having what feels like back contractions for about an hour now. It has gone from an uncomfortable ache to a menstrual cramp feel... lower back up to my mid back... a bad tightening feeling that is constant. With my first, I never went into labor so not sure if this is normal. I would call my doctor but we just moved due to family issues and I don't have a doctor here yet... my other doctor is in south dakota and we are in Louisiana now!! Is there need to be concern or is this normal? When should I start to be concerned? I also have had extreme vaginal discomfort lately as well as low low in my tummy... hard to explain. I have had pelvic girdle pain for about 2 months now and the low pain feels just like that but constant now that my back is cramping.. but it doesnt hurt when i move. Sorry this is so confusing I just dont know how to explain this.
