How many days is a normal menstrual cycle?

The menstrual cycle is very important for every woman, because only a normal menstrual cycle can prove that a woman's uterus or reproductive system is normal. However, since each woman's body has great individual differences, the length of each woman's menstrual cycle is different. However, for most women, they don’t quite know how long the normal menstrual cycle is. Today’s article will explain to female friends the normal length of the menstrual cycle.

The normal menstrual cycle for Chinese women ranges from 21 to 35 days. If it exceeds this range, it is abnormal. Shorter than 21 days is called frequent menstruation, and longer than 35 days is called oligomenorrhea.

How many days is a normal menstrual cycle?

Your question is very important. The reason why we talk a lot about abnormal menstruation is that first of all we need to know what normal menstruation is. If we can make our female friends understand what a normal cycle is, then they can recognize the abnormality themselves.

The current standard in China for a normal cycle is 21 to 35 days. Most women are within this range, that is, their cycle is generally the shortest at 21 days and the longest at 35 days. If it exceeds this range, that is, shorter than 21 days or longer than 35 days, it is abnormal.

If the menstruation is shorter than 21 days, we call it frequent menstruation, and if the menstruation is longer than 35 days, we call it infrequent menstruation. Whether it is frequent or infrequent, it is abnormal. If this happens occasionally, you can observe it. However, if this out-of-range cycle occurs repeatedly, it is recommended that female friends go to the hospital to check the cause and receive standardized treatment.
