I had an estrogen test a few months back, it said normal levels on HRT should be between 75-400. I'm on patches and mine came back at 200 which I was told was normal for being on hrt.
I would say yours is at the low end of normal. I couldn't get on with the gel, it was horrendous, my estrogen hit rock bottom as I never absorbed it and all my symptoms came back.
