Alternative Names:

Home Care:

Keep a record of your menstrual cycles, including when menstruation begins and ends, how much flow you have (count numbers of pads and tampons used, noting whether they are soaked), and any other symptoms you experience. Tampons should be changed at least twice a day to avoid infection.



Because aspirin may prolong bleeding, it should be avoided. Ibuprofen is usually more effective than aspirin for relieving menstrual cramps.
