Menstrual Cycle: Dealing With Cramps
Why do I get cramps when I have my period?
During
your menstrual cycle, the lining of your
uterus 
produces a hormone called
prostaglandin. This hormone causes the uterus to
contract, or tighten, which can cause cramping. Women with severe cramps may
have higher-than-normal levels of this hormone, or they may be more sensitive
to it.
Most women have painful menstrual cramps from time to time. Cramps are more common in the teen years and early 20s. This cramping usually goes away in a few years when the hormone levels even out. But some women in their 30s and 40s still get cramps during their periods.
Sometimes menstrual cramps are caused by a health problem not related to having your period, such as endometriosis or uterine fibroids. To treat these kinds of cramps, you need to treat the health problem that is causing them.
