Clinically, if you want to delay your period, the most scientific method is to take progesterone orally. It is recommended that you start taking it orally five days before your period, taking two capsules once a day. Keep taking it until the time you need to postpone your period, you can stop taking it, and your period will come 3-7 days after you stop taking it. Since progesterone is taken orally to postpone menstruation, it is clinically possible that the volume of menstruation will increase when you get your period, so don’t be nervous. Since dizziness may occur about an hour after progesterone is taken, it is recommended to take it orally before going to bed. In addition, you must remember not to miss the dose in the process of taking the medication. Once the dose is missed, it is likely to cause irregular vaginal bleeding, which will not achieve the purpose of delaying menstruation in clinical practice.
