TSH down to 4.46 and no med increase from endo

Hi all! I have been having medication increases over the past 4 months to get my TSH down. It started at 14.58 and has finally come down to 4.46, just “in range”.

When I went to see my endo for the first time in October, she mentioned that she likes her hypo patients to be around 2.5. So, I was expecting her to bump up my Synthroid once more since I am only juuuust in range but she’s keeping it at 75mcg until my next visit in January.

Should I be concerned about this? I know I am technically normal now but I think I’ve seen a lot of people say below 2 is optimal.
