Lupron depot-ped would not have worked on endometrial cancer. In other words, the lining would have stayed thick inspite of the

Lupron depot-ped if you had cancer. Also, 14mm is a very nice (optimal) number to have if you are hoping to conceive. If you don't conceive, you should have a nice "healthy" period and the lining should become thin again and start over.
Since you are young and premenopausal, your lining should thicken and thin out monthly. If you conceive it will take care of itself. The only time you need to worry about endometrial cancer would be if you are not on any medications, and you are not having your period for prolonged periods of time (eg 6mos to 1 year). Even then, we can usually reverse any changes by giving progesterone orally.
Good luck!
