Needing to Increase Estrogen?

Just wondering how common it is to need to increase estrogen as you go through perimenopause? I am on a 0.05mg patch twice a week and 100mg of progesterone right now. It's where I started and where I've stayed thus far. I am 41 (if it matters).

I've been on HRT for 2? 2.5? years now but recently have started getting hot flashes again and started waking up with a racing heart despite like...nothing going on. I am also EXHAUSTED again and golly it sucks.

I've done everything from stopping coffee to lowering sugar intake etc. Do I just probably need to go up on estrogen again? Is this a thing?
