Over the past four years I have had a handfull of periods lasting approximately 3 days with minimal bleeding and no cramps. My most recent period was back in November of 2015 and was a breeze. I am sexual ly active with only my boyfriend. About 9 days ago I started having excruciating waves of pain in my pelvic area and lower back and then started bleeding heavily approximately 5 days ago and the pain became constant and more intense
