I am 34 years old. About ten days ago I started to have bad lower back pain, then I got my period. I thought the lower back pain would subside when my period had ended; however, it has continued. I am still having some cramping and the lower back pain feels like an intense pressure. I went to a primary care doctor yesterday and they did a urinalysis and some xrays of my back that all came back normal. I had a pelvic exam in March that didn't raise any red flags, but I am wondering if I should contact the gynecologist at this point or if I'm over reacting?
