Introduction
If menstruation occasionally lasts for more than ten days and the flow gradually decreases without significant discomfort such as abdominal pain or dizziness, it may be related to emotional fluctuations or environmental changes, and the body can usually self-regulate and recover. In such cases, it can be considered normal. However, if menstruation frequently lasts for more than ten days, or is accompanied by heavy bleeding, large blood clots, abdominal pain, fatigue, dizziness, or other symptoms, medical attention may be necessary.

Generally speaking, whether it is normal for a menstrual period to last more than ten days depends on the specific circumstances. If it occurs occasionally and without other discomforts, it may be considered normal. However, if it occurs frequently or is accompanied by abnormal symptoms, it is not considered normal. If there are any concerns, it is recommended to seek medical advice in advance. Detailed analysis is as follows:
