Intro and hypothyroidism question

katmacwv

This is my first time on this board.  I'm expecting my second daughter in June.  I didn't have any supply issues with my first, but I wasn't diagnosed with hypothyroidism until she had turned 1 and I was no longer pumping or BF'ing.  I didn't know until today that thyroid conditions could impact milk supply.  I've been on the same dosage of thyroid meds for over 2 years now and my OB has been testing me about every 8 weeks during my pregnancy.  Anyone with hypothyroidism with any advice? TIA.
