I am going on a holiday next week and would like to postpone my periods. can i have promolut -n? will it affect my chances of getting pregnant in future?

Progesterone pill ok: The medication you describe is a progesterone type of medication. It is called Norethisterone. It works by reducing the uterus's endometrial lining. This medication is not usually prescribed, but similar medications can be used. Regular oral birth control pills can do it as well. You must start before your vacation begins. They do not affect future pregnancy chances.
