How can you prevent your period from coming?

Answer 1

If you want to delay your period you can use a medication called Northisterone, which you can get from your doctor, this is a progesterone pill so overrides the progesterone drop that would normally trigger menstruation. You start taking it three times per day from three days before your period is due, and continue until you want your period to start.

Hormonal Birth Control can also be used to stop your period, long-term this is known as menstrual suppression, however using birth control in this way can increase risks and we don't yet know the full long-term risks of menstrual suppression.
