What is wrong with me

So I got off mirena December 2017. I had 8 years two diff devices. I experienced the crash. Hair shedding stomach issues immune disorders etc.

it’s been over a year

I’m turning 33 in July. I don’t feel the dr has been doing the proper test. I’m concerned about my thyroid possibly

My scalp is super itchy. No dandruff. I’ve tried everything. My hair is still shedding but not as bad as a few months ago. I still suffer from chronic fatigue and pms symptoms whenever I’m not on my period. But the two weeks meaning mid cycle.

I’m feeling hopeless. I’m taking vitamins and supplements and trying to balance out. What type dr should I see now?

I had ultrasounds and they said normal. I don’t feel normal. I feel terrible.

Thanks
