If you want to delay menstruation, it is best to take oral progesterone, which can achieve the desired effect. It is advisable to start taking oral progesterone five days before your period, take two capsules once a day, and stop taking it until you think you can have your period, after which you will have your period in 3-7 days. Since oral progesterone delays menstruation, it is likely to cause an increase in the amount of menstruation than before, so do not be nervous. It is also important to note that since dizziness can occur within an hour or so of taking progesterone orally, it is advisable to take it orally before going to bed. It is also recommended to make sure that you do not miss any doses during the period of taking the medication, which, if missed, may result in irregular vaginal bleeding and fail to achieve the desired purpose.
