Thanks for posting your query.
As you are hypothyroid and taking exogenous hormone thyroxine
, you should continue your treatment life long, though dose will be adjusted according to your need. Normal TSH level
should be below 2, however these tests are not very reliable and doctor has to correlate it with you physical findings. Saliva TSH levels are more reliable. In pregnancy
normally thyroid hormone levels change so it is kept in mind while prescribing thyroxine.
Hope it helps,
