Hi Yoti, I had thyroid (hyer) many years back, felt lost and sad when i knew i had to be put on medication till I totally recover (I thought then that it was set for lifetime medication as the doc said). It was mainly my work stress that causes this condition. But i totally recovered a year later, after i keep to my routine daily medication consciously. I have been going for blood test every year on my own account just to ensure it doesn't come back again. 2 years back when i was preggy, i'm diagnosed with thyroid again and i'm the same as you, so worry that it might affect my baby. I was referred to a thyroid specialist at Mount E. The doc is very experienced and professional, makes me feel that he is in total control. He said it is not uncommon for one to detect thyroid during pregnancy, there are 2 types of thyroid condition, one is "real" thyroid condition and that needs medication. As long as u keep to the medication, baby and pregnancy will be safe. The other is a "fake" thyroid condition which seems like thyroid when u take the normal thyroid test, but it's not. u have to take a further blood test on the "free T4" in your body to see if it exceeds the norm, if not, it is a fake one and such condition does not need medication as it will go away after some time. Mine turns out to be a fake case and after a few review sessions with the specialist, i don't have to go back anymore and did not have to be on medication. Perhaps you shd consult a specialist to listen to his views? On either cases, i think as long as you stick to the medication, the condition will be controlled. Don't fret yourself out..k
