How does secondary dysmenorrhea cause menstrual cramps? You feel pain when part of the muscle briefly loses its supply of oxygen. If the uterus contracts too strongly, it can press against nearby blood vessels, cutting off the supply of oxygen to muscle tissue. During menstruation, the uterus contracts more strongly. The uterus, the muscular organ where a fetus grows, contracts throughout your menstrual cycle. Menstrual cramps happen when a chemical called prostaglandin makes the uterus contract (tighten up). You usually don’t have nausea, vomiting, fatigue or diarrhea. Pain from secondary dysmenorrhea usually begins earlier in the menstrual cycle and lasts longer than common menstrual cramps.

Common menstrual cramps may become less painful as you get older and may stop entirely if you have a baby.

You may feel pain ranging from mild to severe in the lower abdomen, back or thighs. Pain usually begins one or two days before you get your period or when bleeding actual starts.
