I think I'm balding?

Hi so I plan to make an appointment with a doctor I'm just out of insurance right now, I am 28, and I have seen a big decrease in my hair these past few years. I have hormone issues because I have irregular periods. And when I got my blood drawn a while back, I had high levels of testosterone in my system.

Anyway, I was wondering if there's anything I can do or eat to prevent the follicles from dying.

My mom's side has very luscious thick hair and my dad's side my aunt had alopecia and she lost all her hair. But my grandma had very thick hair on my dad's side. My other aunt has thick hair as well on my dad's side. Here's some reference photos.

My hair looks thicker on the bottom but up top is concerning. My mom has very thick hair, my brothers still have their hair my one brother is in his 30s and my other one is 40. My sisters have thick hair... but me I don't know what happened.
