Hormonal imbalance years after menopause??

I am 72 and new to this site so thank you for your patience with this question,
I have not had hot flashes for many years. Prior to menopause I used to get PVCs (skipped heart beats) and it only happened around my period so it was hormonally related and they stopped after menopause. Vaginal dryness and tightness also increased after menopause making sex impossible. I also have several rather large fibroids which are smaller now but still a substantial size and they cannot see my overies on ultrasound,
All that said and fast forward, suddenly I started getting hot flashes some days off some days severe. The PVCs started back again, some days off some days severe. I had some spotting once.. end of day most likely from atrophy but discovered very tiny cyst on one of my overies. So all odd things hormonally related.
I saw all my docs.. my gyn wants to give me vaginal estrogen, I told her I was concerned about the fibroids growing and she stated that its local and not systemic... however I have used it many yrs ago and my fibroids did seem to get bigger so I stopped. She has no clue re the hot flashes but wanted to give me meds for them. I said no.
I told her I had ordered a hormonal panel thinking maybe my hormones are askew more than ever for some reason. Adrenals? She said, we know what your hormones are like now and the test is not useful. mmm?
One thought I had was to seek out advice from an endocrinologist.
This past weekend I had severe burning below and thought it was a UTI but then I took a look and my vagina inside and just outside had tears and slight bleeding. I used some aquaphor and its somewhat better and have messaged my doc.
SO I have three questions.
Has anyone ever had this combo mess that I am experiencing?
I read on this site about coconut oil so will explore that but has anyone used Juvi gel?
Is anyone post menopause with fibroids and vaginal atrophy using estrogen cream and what is your experience.
Has anyone ever had hormonal fluctuations years after menopause.

I feel we need to be our own doctors in a way, research and learn because our docs are so busy and so focused on their specialty I am not sure they are the systemic problem solvers docs used to be. It seems all they want to do is test and give meds. Sometimes necessary sometimes not. Thank you for reading and please share any similar or relevant experience.
