Dysmenorrhea is the term doctors use to talk about the pain we feel during menstruation. It can be "primary" (the most common, caused by natural uterine contractions) or "secondary" (when there's something else, like endometriosis). Knowing the technical name helps you talk better with your gynecologist. Remember: feeling pain is not something you should accept as "normal" if it's very strong. There's always a way to relieve it!
