I think that all females have experienced the periods from hell...
I had three remedies for a couple years... First, as said, stay active (jump around, walk, etc), Second, curl up into fetal position after taking ibuprofen. Third.... BigMac meal from McDonalds. That always helps... greasy food.
Then my doctor suggested birth control to help regulate. I'll tell you, while I was one them, it was heaven on Earth. I had cramps only my first day that went away with aleve/ibuprofen. Plus, my cycle was only three days long, tops.
After I went off them, I was pretty regular too, and the pain had been alleviated. So, if you want, that's a good way to go.
Another good way to get rid of cramps during your period is to just get pregnant! LOL. It's really weird right now, having gone without it. It's very strange, yet relaxing! 🙂
