given that you are on levothyroxine
do not adjust dose without testing the free t4, tsh
levels. as you are on hcg
which can have such changes, not only tsh but even free t4 would be required to adjust doses. doing that without testing can be harmful.
important for you to realise that do not expect to be off all medications. thyroxine is a very safe medicine taken life long. and if your body requires the doses no point stopping it.
hope this is helpful
