How to increase estrogen, if testosterone is well suppressed?

Hey everyone :D

Sooo I've been on HRT for 4 months and after horrendous first test results on only estrogen and a GnRH-suppressor, this time they seem okay?

Testosterone is at optimal levels at 0.27 ng/ml, but estrogen (E2) is only at 49 pg/ml 8 hours after my last dose. :/

I know it's not horrible, but sure could be much better. So now I'm thinking about increasing my estrogel dose on my own, as my endocrinologist prefers the slow and steady approach and I already added two pumps of estrogel on top. Changes up until now have been barely noticeable, but a few days ago what I think are buds are beginning to form.

I'm currently on 4.5 mg of estradiol (6 pumps per day) in the form of estrogel, spiro 50mg pill, a GnRH-suppressor injection (Trenantone) every 3 months and a 100 mg progesterone pill that I boof.

TLDR: Testosteron levels are optimal, estrogen in the lower ranges. Should I increase my estrogel doses or am I simply too impatient? Any other tips on upping my estrogen levels are welcome. :)
