There are some women whose periods are delayed almost every time, and it is generally normal to delay your period for about 3-7 days. The onset of menstruation usually lasts 3-7 days, with 7 days being the duration of most women's periods. During the entire period, days 2-3 are when the amount of menstrual blood is the heaviest, and you will need to change about 4-5 sanitary napkins a day. The color of menstruation is usually dark red, and in some women it is bright blood red.

Normally, if your period doesn't come for more than 7 days, you should pay attention to it. The hormonal changes in the body can cause your period to be delayed or advanced. For example, endocrine disorders caused by stress or medication can affect estrogen secretion in the body, thus delaying your period.

Additionally, if you are pregnant, you won't be able to get your period, so if your period is delayed for more than a week, then it is possible that you are pregnant, and you need to go to the hospital to check the cause of your delayed period and determine if it is delayed because of pregnancy.

For some women who get their period on time every month, if there is a sudden delay, you don't need to take any measures within 7 days. If it's more than 7 days, you should first rule out whether it's due to environmental, medication or dietary factors. If it's due to one of these reasons, you can wait for another 3 days or so to see if your period comes back.

If it's been more than 10 days since you've had your period or if it's not one of these reasons, you need to go to the hospital for a checkup to determine if it's due to gynecological inflammation or disease.
