Mazal Tov on your 30th anniversary!
It is possible to take Primolut or similar progesterone-only medication (such as Aygestin in the US) to
induce a period. Usually the pills are taken for 5 days and then you should expect to begin bleeding a few days after stopping. Please discuss the specifics with your physician, explaining that you will need to stop bleeding at least 8 days before your trip.
Please feel free to get back to us with any further questions.
B'hatzlacha!
