“How do you stop period cramps?”

Best to try NSAIDS such as ibuprofen.

See an Acupuncturist.

A lot of women suffer from painful menstrual cycle. This is called dysmenorrhea. It is not always but sometimes an indication of possible endometriosis. I would recommend telling your primary care doctor or gynecologist about your symptoms to see if there’s something they can do. If the pain is severe then I recommend seeing a pain management doctor Who deals with Pelvic Pain.
