Answer:
Depo causes many horrible things to happen to a majority of women's bodies, so I would NOT be surprised if depo was the cause.
If they can't find out what caused your thyroid problem, I would truly believe that it is the depo causing it.
My mother had her thyroid removed a few months ago. She wasn't on any medications and it came about quickly. There is no family history of any thyroid problems. I have been on depo for years and haven't had any problems despite my mothers problems. I wouldn't be so quick to blame it on your birth control.
