2nd trimester - Am I being overtreated for hypothyroidism?

I was diagnosed with hypothyroidism around week 13 and started on levothyroxine 100mcg. I am now almost 17 weeks and my repeat TSH 0.12! That seems really low … can anyone else confirm whether that is too low or expected for second trimester? I am still waiting to hear back from my endocrinologist :( Getting worried I might be overtreated and thought about stopping the levothyroxine until I hear back but who knows when that will be !

Would appreciate any insight on this! So scared

Also want to add my T3/4 are normal though! So Im really confused
