How long do period cramps last?
Cramps often begin just before a period starts. They can last for the whole period, but tend to be worse at the beginning and when the flow is heaviest. Most often, pain is felt in the lower abdomen and lower back, but it sometimes radiates to the thighs. Cramps can usually be improved with over-the-counter pain medication, exercise, and warm baths or hot water bottles.
Not everyone gets cramps, and some people have them for the first few years of having their period, and then they get better. Other people start out with pain-free periods and start getting cramps when they’re older. But a review of 15 studies conducted between 2002 and 2011 found that it’s more common for symptoms to decrease with age and after childbirth. The female reproductive system can be unpredictable!
