Cramping during your period is normal. Take ibuprofen (motrin) for the cramps. Heating pads, also, help. The cramps occur due to inflammation of the tissue in the uterus. It is just part of being female.

im not retarded, i have had my period for years and know what cramps are... i was just wondering why they are all of a sudden different

Are you on birth control? Birth control can cause really really really bad periods, and behavior changes and all kinds of crap. I hope you feel better.

Well how old are you? If you are still in your teens, you can have quite a big difference in your periods from one year to the next. Mine didn't start to actually hurt for about 2 years when I first got mine. If you are having sex, they can change. If you've had a baby they can change. If you feel like something is wrong, then you can always tell your doctor, it never hurts to get things checked out....
