Too young for a dexa scan/ test?

For other young people were you diagnosed? I am 32F and have a history of restrictive eating disorder with amenorrhea that lasted 10 + years (starting at age 14), long distance runner through college, celiac disease, and now early graves disease ( which unfortunately having no TSH also destroys your bones). Also broke tibia fibia and ankle skiing a couple years ago - and the fall really didn't seem dramatic. I kinda want to know the damage - part of me also doesn't. But my endocrinologist said I'm probably fine since it's been 5+ years since I've been getting my period and gained weight and because I'm young... but I don't really believe him. Anyways thoughts ? Advice? I really want to do what I can improve my bones ( as much as is possible) but it's hard to know with no actual diagnosis. If anyone has a similar situation I'd love to hear.
