All the best. I'm not pregnant or TTC#2 yet but I was diagnosed with hyperthyroidism about 3 months ago and then it changed to hypothyroidism a few weeks ago - without treatment. Now I'm on thyroxine (currently 50mcg) but being monitored by my GP until I can see the specialist in a month. I'll be interested to read about yours and other people's experiences with thyroid issues and pregnancy.
