Is Missed Period With Depo Lupron Sign Of Premature Menopause?

Hello Doctor, I was put on depo lupron due to fibroids that cause me anemia and I had to get a blood transfusion in January 2010. That same month and time I was given depo lupron every three months which I think came out 2 a total of 2 shots in a 6 month period. It is near or about a year and I still have not had a period. Is this something I should be worried about because the new doctor I seen sad something about the depot lupron may have put me prematurely into menopause. Please help ease my fear and worry. I am 37 year old.
