Auntie refers to menstruation, which usually comes once every 21 to 35 days, or it may come once every 21 to 42 days, depending on the person, and may be related to emotions, work and rest, and other factors.
How often does menstruation occur refers to the menstrual cycle, that is, the time between the first day of menstruation. Usually, menstruation occurs once every 21 to 35 days, and studies have shown that the average menstrual cycle is 28 days. However, in some cases, it may also come once in 21 to 42 days, so a seven-day advance or delay in menstruation is within the normal range and is not a cause for undue concern.
To summarize, there are obvious individual differences in the timing of a woman’s menstrual cycle, which may be related to emotions, work and rest, the environment and other factors. Generally speaking, as long as a woman’s menstruation maintains its own regularity, it does not belong to the menstrual irregularity. If menstruation is delayed for more than seven days before the onset of menstruation and you usually have sex, you need to be vigilant about whether you are pregnant.
If the menstrual period is irregular and there is abnormal vaginal bleeding, you should go to the hospital in time to improve the examination, to clarify the cause of the disease and carry out targeted treatment.
