Hi, Thanks for posting in HCM. I understand your concern. You can use Norethisterone medication for postponing the periods. You may take it for 3 or 5 days, following which you would get your periods. It would not affect your fertility or cause any hormonal imbalance. The dates of your cycle would change and hence you need to time accordingly if you are expecting to conceive. Hope the information provided would be helpful. All the best.
