Hello ma'am and welcome.
Yes, it is required to take norgest
to help with your menstrual cycles. But it is completely upto you whether you choose to take this medication or not.
As for conception, hormone levels should always be normal or close to normal for everything to go well, especially something as important as conception. It is first important to normalize ypur periods and then go ahead with conception, so please dp as your doctor advises you.
Hope this helps.
