How to calculate the next menstrual period after it comes early

How to calculate the next menstrual period after it comes early? Calculating the time of the next menstrual period according to the regularity of time can only be used by people with regular menstruation, that is, the menstrual period is regular. A regular menstrual period is 28-30 days or 26-35 days. If you have a regular physiological cycle, this menstrual period should be calculated from the first day of menarche, and the next menstrual period will come 4 weeks later.

For example, if the menstrual cycle is 28 days, then 4 weeks later from the first day of your period, you should have your period on the 28th day. There may be a difference of 1-2 days before or after, which is all normal. Sometimes, due to changes in mood, fatigue, sleep quality, living conditions, etc., the menstrual period may be advanced or delayed, but it will not exceed 1 week. If it exceeds 1 week, you need to consider whether it is a pathological condition, such as pregnancy, menstrual disorders, etc. If you have a normal, regular menstrual cycle, you can start counting from the first day of your period and follow the normal cycle. If it is usually 28 days, then count it back 28 days. If it is usually 35 days, then count it back 35 days.

How to calculate menstrual period

In most cases, the menstrual cycle is calculated based on one month, but this will vary from person to person, and some people have different menstrual periods. Generally speaking, a menstrual cycle is basically within 21 to 35 days, with an average of about 28 days.

Menstrual cycle time

1. Average 28 days

The normal menstrual cycle is about 28 days. Sometimes it is early or delayed, which is relatively normal and there is no need to worry too much. Therefore, a menstrual cycle of no less than 21 days and no more than 35 days is normal. After all, the length of the follicular phase of each woman is completely different.

2. Menstrual period lasts 2 to 8 days

The time of menstruation is not fixed, it is generally about 2 to 8 days, and the average is 4 to 6 days. If the menstrual period is relatively normal without any special abnormalities, and the menstruation is suddenly advanced or delayed, then this is a case of irregular menstruation and needs to be actively treated.
