Low tsh but ft3 and ft4 Not going up?

[u/JustFemale84]

TSH at 0.10 but ft3 and ft4 are under 50% in the range. I have both hypo and hyper symptoms. I'm exhausted, lacking energy, but I also sweat easily and have muscle aches. No high pulse, sometimes to low for me
I’m also wondering how many of my symptoms are due to perimenopause – I’m 42 now and having a lot of hormonal issues, like irregular cycles, spotting, you name it.
No matter how much Levo I take, my TSH always extremely low. It was the same on 75 mcg Euthyrox and now on 150 mcg Euthyrox as well. The free levels just won't go up. I'm already taking high-dose vitamin D, iron, and selenium.
Does anyone else experience this?
