For all the girlies with periods, how bad are your cramps?

After I had my children, like before I had my kids, my cramps were absolutely terrible. I legit had to stay home from school. When I went to high school, I went to Townview Magnet Center and they actually had cots lined up about six of them where you could lay down. They had heating pads attached, so I would be in there the first day especially. But after having my children, they have calmed down tremendously. I really don't even feel them anymore.
