At the beginning of puberty, girls show their menstrual cycle, which is repeated every month, called the menstrual cycle. Paying attention to the pattern and frequency of your menstrual cycle can help detect symptoms of a number of health problems.

1. What is a normal menstrual cycle?


Menstrual cycle is counted from the first day of appearance to the beginning of the first day of the next cycle, usually 28-30 days. A short cycle that repeats at regular intervals after 21 days or 32 to 35 days is also considered normal.
The length of a cycle is usually 3-5 days, lasting from 2-7 days is also acceptable. Menstruation beyond 7-10 days is also called normal if the amount of menstrual bleeding is very small.
There may be slight variation between cycles considered normal. For example, if your last menstrual cycle was 28 days and your next cycle was 30 days, this is also within the normal range. Sometimes due to stress or illness, a woman's menstrual cycle can be delayed and you don't need to worry about missing a period. But you need to see your doctor if you regularly experience irregular periods for more than 40 days or longer without becoming pregnant.

2. Irregular menstrual cycle


Everyone's period is very different. In some people, menstruation lasts only two to three days, but in others it can last seven, eight days or more. When experiencing abnormal conditions, women need to go to a medical facility to be examined, find the cause, and take timely treatment measures.
The phenomenon of menorrhagia when menstruation is heavy and lasts for more than 7 days, having a cycle is considered abnormal.
Bleeding is also bleeding that lasts more than 7 days but is not cyclical. Menorrhagia if it lasts for more than 15 days will become heavy bleeding and is called menorrhagia- menorrhagia. This phenomenon can have serious health effects. Therefore, when there are symptoms, women need to go to the hospital for examination to determine the cause and timely treatment.
Hypermenorrhoea is a condition where the amount of menstrual blood is both heavy and lasts for many days, affecting women's health because it causes a lot of blood loss.
Amenorrhea is a condition in which the amount of menstrual bleeding is small and does not last long, usually for 1-2 days

3. How much blood is normal?


Although a woman can lose a lot of blood during her period, in reality the average woman only loses 2 tablespoons of blood during her entire cycle. 4-6 spoons is also considered normal. If you have to change your tampon in the middle of the night or if you have a very large blood clot (the size of a golf ball or larger), that's unusual. Small blood clots that may appear on the first or second day of a menstrual cycle are considered normal.
Normally on the first day of your period there will be more menstrual flow, but not so much that you have to change your tampon every hour or every two hours. If you find that you need to change your tampon every 2-3 hours, see your doctor right away.
