How to reduce menstrual cramps 
Take over the counter medication. 
Nonsteroidal anti-inflammatory drugs (nsaids) such as ibuprofen or naproxen are the first-line medicines for painful menstrual cramping. Nsaids work by blocking the contractions that cause cramps.
Ibuprofen is the most common of the two. You can take 400-600 mg of ibuprofen every 4-6 hours or 800 mg every 8 hours with a maximum dose of 2400 mg daily.
