Why do doctors act so clueless?

Anonymous
Every time I have a doctor appointment or have an ER visit, they ask the basics (Height, weight, what meds I'm taking).

So after the nurse asks the basics, she asks when my last period was. Well since I'm using depo, I don't have periods anymore.

WHY do they always say "What's the reason?" Or something along those lines? Do they not know depo eliminates periods? They went to med school for 6-8 years, right?

They do this to me a lot. Quite annoying.
