Dear Dr. Kate,

Why is my period worse some months more than others?

— Bloody Mary

Dear Mary,

Blame normal fluctuations in your hormone levels. Sometimes your uterus is stimulated with more prostaglandins, the chemicals that cause cramping, so you’re hitting the Advil bottle more than usual. And if your lining is thicker one month than another, you’ll see heavier bleeding and sometimes even clots. Variations like these are normal, albeit a pain to deal with. The easiest way to get predictable periods (both in flow and comfort) each month? Most hormonal birth control methods, especially the vaginal ring and the progesterone IUD (Mirena). They’ll make your periods lighter, shorter, and less crampy.
