Should I increase my estradiol patch dose above 0.05?

I started at the .025 but still had hot flashes, there was definitely an improvement than when I was on nothing, but my doctor upped it to .05. Then I had zero hot flashes for a few months, but now I’m having 2 or 3 per day, usually when I’m waking up, but not nearly as long or hot as they used to be.

I feel I can easily deal with the few small daily flashes but am worried, will they get worse? Are there any side effects with upping it, like additional weight gain or hair loss, etc.

I’m also on 100mg progesterone nightly.
