I was wondering if someone could help me. I'm 35 weeks pregnant, no thyroid and currently taking 200mcg levothyroxine. Earlier in the pregnancy, my levothyroxine dose was reduced to 150mcg which resulted in my t3 and t4 going down and I felt dreadful. Despite my tsh being low, the doc put me back up to 200mcg and feel really well but my tsh is 0.05 (t3 is 4.2 and t4 is 12.1). Is there any risks with my tsh being so low?
