Having cramps once you're past 37 weeks may mean you're in the early stages of labour. At this stage your pregnancy has reached term, so the cramps are a normal part of your body gearing up to give birth.
Common menstrual cramps often start shortly before or at the onset of the period and continue one to three days. They usually become less painful as a woman ages and may stop entirely after the woman has her first baby.
