What type of doctor should I see first?

I have been having some health issues and I’m wondering what type of doctor would be able to best address my concerns. I stopped birth control pills about 6 or 7 months ago and I have had no period still. My gyno told me she felt a cyst on my ovary. Not sure if this is related to the absent period. Also, ever since stopping the pill, my skin has been breaking out terribly. To me, these both sound like a hormonal imbalance issue. So if that’s the case, what type of doctor should I start with? Is there a one stop shop for my issues or should I see a dermatologist in addition to a gynecologist? Or maybe start with a general doctor? I have tried my general doc in the past for issues and she only treats the surface issue, not the root cause. For skin, she will give me a cream or antibiotic. For irregular periods she will put me on the pill. I want to find out why I am having breakouts and an absent period. I don’t want a quick fix again.

I recently switched insurance and I am waiting for my new insurance to kick in. So while I’m anxiously anticipating that, I am going to call and set up a doctor appointment(s) because I assume it can take a month or two to be seen.
