Well, I will describe my experience with them in two ways. With my first, I was young and had not experienced any
period cramps before. So, when people said they feel like strong period cramps, I was still unprepared. To me, at that time, they ended up feeling like extremely strong cramps for a bowel movement. The kind you get when you have an extremely upset tummy but more intense.
Now, however, I have experienced painful menstrual cramps, and people described it pretty accurately.
