I usually take ibuprofen for menstrual cramps but last time I took it I got bad stomach cramps for several days. I think it messed with my stomach lining. Though I'm not 100% it was the ibuprofen that did this, I'm pretty sure it was. This time for menstrual cramps, should I take lower doses of ibuprofen or is there anything else I can take that works well? (I can't take acetaminophen because it never works for me).
