Disease description:

My menstrual cycle has always been regular each month, and my flow has been normal. But this month, my period came with an unusually heavy flow—I've been bleeding continuously for a long time and it just won't stop. I'm starting to wonder if something might be wrong with my body. So, how long does a typical menstrual period last?

Menstrual duration varies from person to person, but generally lasts 3 to 7 days. As a rule, individuals with a smaller uterus and thinner endometrium tend to have shorter periods and lighter menstrual flow. Menstrual volume may increase and the period may become longer. In certain cases, conditions such as uterine fibroids or other factors that thicken the endometrium can lead to heavier menstrual bleeding and prolonged cycles. If your body shows any abnormalities, you should seek medical attention at the hospital promptly.
