"How much blood do you have to shed on a menstrual holiday?" I came out of the bathroom and said to my girlfriend worriedly, "I just looked at it when I was changing the tampons, and I felt a lot of blood." ”
The girlfriend thought about it and said, "500 ml at a time is like a bottle of mineral water." ”
Well, it seems to be similar to how I feel.
Later, I saw that the "Obstetrics and Gynecology" wrote in black and white that "the normal menstrual amount of women is 20-60 ml, the total blood loss of a menstrual period is more than 80 ml, and when it is less than 5 ml, it is less menstruation", and I can't believe it for a while.
How much is 60ml? Pour 60 ml of coffee into a 550 ml mineral water bottle and look at it:

That's it? Can't do it! My menstrual volume must have exceeded this number, is there something wrong with it?
How much blood was shed on a menstrual holiday? Do the math
Usually when going to the hospital for examination, the doctor will roughly assess the amount of menstrual blood based on the number of tampons or sanitary napkins used during menstruation. Although I was worried about my excessive menstruation, but I didn't want to go to the hospital, I found The menstrual pictogram and prepared to wait until my next menstrual period to actually calculate my menstrual blood.

Finally, on a Sunday afternoon in August, the calculations can begin!
The procedure for calculating menstrual blood volume is not complicated: record the number and use of sanitary napkins (tampons) used every day, and calculate the sum according to the correspondence in the table. It should be noted that when changing sanitary napkins (tampons), the blood dripping on the toilet and the blood lost by blood clots need to be counted.
The period lasted a total of 5 days. During this time, I used tampons with the model number "regular". In order to facilitate counting, I reduced the frequency of changing tampons, so that each tampon could be infiltrated by menstrual blood as much as possible, so as to avoid the situation where a tampon was only stained with a little blood, because such tampons could not be counted.
It may be that my uterus knows to do a big project to record the amount of menstrual blood, and this time it was unexpectedly sensible, and there was no case of menstrual blood dripping on the toilet when changing tampons. The recorded data is shown in the figure below:

In the end, the amount of menstrual blood I measured was 36 milliliters, which was far from the standard 80 milliliters of menorrhagia.
It turns out that the gushing of blood is probably an illusion.
What should I do if I have too much or too little menstrual blood?
Some people really have more than 80 ml of menstrual blood, is this a disease? For this question, I am afraid that there is no clear answer here.
There are certainly some diseases that can cause excessive menstrual blood volume, such as uterine fibroids, uterine polyps, and polycystic ovary syndrome. However, menstruation involves complex hormonal and endometrial changes, and a significant proportion of healthy women also have excessive menstrual blood volume, which may be related to age and hormone levels.
During the normal menstrual cycle, estrogen and progesterone regulate changes in the endometrium. When estrogen and progesterone are out of balance, it can lead to excessive menstrual blood volume. Adolescent and perimenopausal women are more likely to experience excessive menstrual blood due to estrogen-progesterone changes. An IUD (UTER) may also cause excessive menstrual blood volume in some women.
Some people worry that they have too much menstruation, and some people worry that they have too little menstruation. In fact, according to the previously mentioned definition, only menstrual blood volume is less than 5 ml can be called too little menstrual volume. After taking some contraceptives, women will experience a shortening of menstrual duration and a sudden decrease in menstrual blood volume. When there is adhesion in the uterine cavity, it can also lead to too little menstrual volume.
If the amount of menstrual blood suddenly decreases or increases, and lasts for several months, there is no need to be too nervous, what we have to do is to record the changes in our menstrual volume and go to the hospital in time.
By the time of your next menstrual leave, are you interested in actually calculating your menstrual blood volume?
