Sometimes I have monster ones too, but never that big. A friend of mine also had heavy periods. It got really bad at one point. Her body couldn't release the blood fast enough. So with each period, there was still tissue in the uterus, and it built up. Her doctor put her on the pill to regulate. When I had monster cramps it was because i drank too much soda. I don't know it was the caffine or the other chemicals in the soda. But I cut down, the cramps were a lot easier.
