You have not told why Depomedrol injections was given to you. If it was given for severe arthritis
pain & it was the only cure available, the use of it is justified. You have not mentioned your age and how many children you have. As inj depomedrol is given periodically it will affect your menstruation
So a balanced thinking and treatment is needed that depends on your basic problem for which Depomedrol was given. If you want to get your periods once again a complete hormone analysis and consultation with an endocrinologist
along with gynecologist is a must. Think and act accordingly.
