There are two types of dysmenorrhoea: primary dysmenorrhoea and secondary dysmenorrhoea. Primary dysmenorrhoea is another name for common menstrual cramps. Cramps usually begin one to two years after a woman starts getting her period. Pain usually is felt in the lower abdomen or back and can be mild to severe. Common menstrual cramps often start shortly before or at the onset of the period and last for one to three days. They usually become less painful as a woman ages and may stop entirely after the woman has a baby. Secondary dysmenorrhoea is pain caused by a disorder in the woman's reproductive organs.
