Good morning, last night i started my menstrual cycle, on the exact day that i was supposed to. however the pain i experienced was something i have never experienced before, i was in excruciating pain and it felt as my inside were falling out?

Pain w/ menses?'s: Sudden onset of pain with the first day of menses without a prior history of same, at 27 years of age may be secondary to expressing a large clot through a constricted cervical canal. At 27, higher estrogen levels may thicken the lining of the uterus, and when it degenerates at onset of menses, bleeding may be more brisk and clots tend to form. BCP's may be better if this persists.
