What a good thing to delay your period?

Answer 1

Norethisterone can delay your period, you'd need to get this from your doctor.

Norethisterone is a progesterone pill so it overrides the progesterone drop that would trigger menstruation, you take it three times per day from three days before your period is due and continue use up until you want your period to start - once you stop taking the pill there is a sharp decline in progesterone levels which will trigger your period to start.
