Estradiol Sensitive Test

Can i get some feedback please? I started TRT 1 month ago. My doc never tested my Estrogen so I went ahead and got my Estradiol Sensitive test done. The result was 9 pg/mL on a scale of 3-70. I know this means my Estrogen is very low, and too low can be bad. Thing is, I have never taken an AI before, and Ive only been on TRT for a month, so how can my Estrogen be this low?

Im 6’1 200lbs, 33 years of age, and have less than 10% bodyfat. My t score a month ago was 218.
Need your thoughts…thanks
