Is it normal for menstruation to last four days?

As long as the amount of menstruation is within a reasonable range, it is normal even if the menstruation is clean for four days. Generally speaking, the normal menstrual cycle of women is 28 days, 3-7 days each time, 30ml-50ml each time, which is roughly reasonable within this range. If women are in puberty, their menstrual cycle may be relatively irregular.

Menstruation is the periodic shedding and bleeding of the endometrium caused by the cyclical changes of the female ovaries. Normal menstruation has obvious periodicity and self-limitation. Generally speaking, the menstrual cycle of adult women is 28 days, 3-7 days each time, no more than 5 days ahead of schedule or delayed, and the amount of bleeding each time is between 30ml-50ml, not less than 20ml and not more than 80ml. Even if a woman's menstruation is clean for four days, as long as the amount of bleeding is normal, then there is no problem with the overall menstruation, so don't worry.

Some women may have very irregular menstrual cycles, very little blood, or even spotting, which may be caused by insufficient blood and qi. They need to take some blood and qi supplementing food or medicine appropriately, and strengthen daily exercise to ensure physical condition. On the contrary, if women have a relatively large amount of bleeding each time, they are likely to have symptoms such as anemia and hypoglycemia. They can carry some sugar or chocolate during menstruation to replenish energy.

As long as the amount of bleeding is within a reasonable period, a four-day menstruation is normal. It should be reminded that women should eat less spicy and cold food during menstruation and avoid strenuous exercise, especially abdominal exercise. In addition, women's menstruation is easily affected by emotions, weather, environment and other factors, so you should pay attention to weather changes and be less angry.
