I am expecting my menses in two days, but i am experiencing severe cramps....what do i do to stop this?

OTC : If this is recurrent, reasearch suggests beginning nsaids (such as advil) even before your symptoms start (assuming you have a regular cycle). This assumes you can take such meds. Follow label instructions and take with food. You may find relief from a bath, or heating pad as well. If severe, consult your ob/gyn about birth control or other options than may make more manageable long term.
