Your diagnosis is probably right. You must be suffering from post partum thyroiditis
. If your antibodies
are positive you have a high chance of progressing to hypothyroidism
In this case what I do is periodic thyroid function tests
every 3 months, and start you on medications when your T4 is low or TSH is above normal.
Hope I have answered your question. If you have any further questions I will be happy to help.
