I take ibuprofen before or during my period. my period began sunday morning, and i took ibuprofen. a couple hours later my period stopped. help?

Not uncommon: As ibuprofen can reduce the volume of menstrual blood loss by 20 to 50 percent. It seems to work by reducing prostaglandin synthesis in the endometrium(uterine lining) which leads to vasoconstriction(blood vessels constrict) and reduce bleeding.

Stopped period: If your periods stop or become erratic and you are not pregnant. There might be a few reasons. 1. Poly Cystic ovaries PCOS--most common hormonal cause-irreg periods,facial hair,acne. 2.Thyroid Dysfunction-hyper-or hypothyroid affects periods 3 weight loss and over exercising --sudden wt loss or over exercising affects menstruation 4 meds:-depression med-or skipping sugar/placebo in bcp5. stress
