If you need to postpone your period, you usually choose the way according to the reason why you need to postpone your period, and the common ones are as follows: 1. Travel or exams: Some women need to postpone their periods due to considerations such as going out to travel for convenience, or due to physical exams, etc. Doctors will give short-acting contraceptive pills to take until the travel is about to end or the exam is over, and the period will usually come about 1 week after stopping the pills. It is also important to note that you should not take the pill today if you need to postpone your period tomorrow, as the short-acting contraceptive pill does not contain high levels of estrogen and progestin and takes some time to work. If there is a need for this, it is best to go to the hospital for consultation about 1 month in advance; 2, after myomectomy: If the patient is worried about the excessive amount of menstruation in the first month after myomectomy, which affects the recovery of the wound, you can take mifepristone and take it for about 3 months in a row to postpone menstruation and let the uterine trauma recover better; 3, endometriosis: In order to let the patient’s ovaries rest To reduce the chance of recurrence after surgery, GnRH-a class (gonadotropin-releasing hormone analog) drug therapy can be given, which can also achieve the purpose of delaying menstruation.
