I am currently 34 weeks and on Thursday I went into my doctor’s office because I was experiencing lower back cramping. It was not severe, but I had never had it before so I thought it best to get checked out. They tentatively diagnosed me with a bladder infection at that time, and said that was the cause of the cramping, but they said they needed to send my urine for testing and would be able to confirm the results at my appointment I had today. Well the test for the infection came back negative, so now I am back to not knowing the reasons for these pains and it makes me nervous. When I got checked out last week, baby was fine and I wasn’t contracting, so I’m not really worried about pre-term labor at this point, but I know there are other potentially serious things, like kidney stones, that can cause lower back pain…but my doctor did not seem concerned and didn’t look any further into the issue other than to suggest physical therapy for the discomfort, as he said that one of the most common complaints late in pregnancy is lower back pain…
So does anyone know of any other causes for this kind of mild, crampy pain? What needs to happen before I go back to the doctor and ask them to please determine the cause officially?
