You can usually delay your period by taking progestin. Clinically, we encounter many women who have special periods or girls who want to postpone their periods in high school. For this phenomenon, you can generally take progestin orally about 10 to 14 days before your next period, and start taking it at least a week or so in advance, such as progesterone capsules, 2 tablets per day, twice a day, and keep taking it orally until you stop taking it when you want to have your period, this method is generally feasible, but it is not guaranteed to apply to all women, some Some women may still get their periods on time after taking the medication. Alternatively, some women can take progesterone or a combination of short-acting contraceptives (e.g., Mafron or Eusebio) once a day, one tablet at a time, until they stop taking the pill on the day they want to have their period, after which they will have their period normally. Or take mifepristone orally once a day, half a tablet each time, until you stop taking it on the day you need to have your period, and your period will return 3-5 days after you stop taking it. It is important to note that if some women have irregular periods or early periods, less than a week before their period, it is unlikely that they will be able to delay their periods with medication, because the medication will no longer work to delay their periods. In short, you can postpone your period by taking progesterone or progesterone or short-acting contraceptives (Mafenone, Eusebio) or mifepristone, but be careful to start taking the pills at least a week in advance, as too short a time will not achieve the effect of postponing your period.
