Is it normal to have a period for four weeks?

It is not typical for a period to last for four weeks. Typically, a period lasts between three to seven days. A period that lasts for four weeks is considered prolonged or abnormal and should be evaluated by a doctor. Heavy or prolonged periods can be a sign of an underlying condition, such as uterine fibroids, hormonal imbalances, or even pregnancy complications. It's important to see a doctor if your period is lasting for four weeks or more to rule out any potential health issues and get appropriate treatment.
