Rough visit to the dr :( anyone have any insight?

:( I went to the doctor today to try to find out why for the first time in my life I missed my period but an not pregnant. No luck. All she seemed to tell me was how overweight I am. I am well aware of my weight issues, I was looking to find out why out of the blue I missed my period. No help at all.
Now instead of trying to be positive about ttc all I can focus on is my weight and feeling bad about myself.
She did a pelvic exam and all good there and she took some blood but does not expect to gleam anything from the results.
Has anyone had any luck in finding a provider who will be supportive of a plus size pregnancy? I feel so downtrodden :(
Sorry to rant, just need some insight from other plus size ttc ladies.
