This is common. It is the referral pattern of the uterus to the back. ou may have a retroverted uterus. NSAIDs, such as Ibuprofen and Tylenol, and heat are helpful for this problem. Also, consider seeing your gynecologist for workup of possible PMDD.

Pain during menstrual cycles are likely sign of gynecological pathology. Could be an ovarian issue or endometriosis for example. My recommendation is to see your OB/Gyn. She/he may order an ultrasound to assess the matter further. I know it's not as helpful when these answers tell you to see your doctor, but I hope the advice helped a little.
