Thyroid issue

Anyone developed a thyroid problem while pregnant. I had hyperthyroidism about 10 years ago and never a problem but since I became pregnant I have felt horrible and been thinking it was just first trimester crappy ness . The not breathing the fatigue , headaches, sore muscles , gitery, lightheaded. And more but last blood work should my tsh levels out of range and I just did the t4 test and waiting for my results.

So if u did develop how did u feel? Is this all cause my thyroid? Maybe
