I would have thought I was having pre-term labor in my back last night. It felt like back labor in every way. I hadn't done much of anything physical yesterday and didn't do anything to strain it. But for 2 hours last night, I was rocking my hips while laying on my side and it was so nagging and coming and going that I was almost in tears. I was about to call my care provider when out of the blue, it just stopped. Before I had the pain, I had an aching "down there" like I was having a period. That and the coming and going of the low back pain is what worried me. Anyone else ever get this? Can anyone shed some light on what may have been going on?
