I am very anxious that my baby will have problems.
I found out I was pg late (7 weeks). When I saw the GP, I collected some old blood test results that must have been taken at about the same time I conceived. They showed I had a "slightly low" thyroid level (ie, elevated TSH), but I can't remember the figures. My GP sent me off for tests, which showed I had high antibodies as well as elevated TSH, so she immediately put me on 50mg of thyroxine.
She didn't seem worried so I didn't worry, and just took the drugs and got on with feeling ill and tired all the time (oh, first trimester!)
Now I'm at 12 weeks, and finally googled "low thyroid levels pregnancy". Now, I am panicking as I read that it can cause problems including mental retardation, if thyroid levels are low in the first trimester! I"m past the miscarriage risk, but it sounds like first trimester is the key phase for thyroid levels in pregnancy.
Will go back to GP to get referral either to OB or to an endocrinologist, as I need reassurance. I would have a termination rather than have a child with a serious disability. (by serious I mean life-threatening or severe mental handicap).
does anyone have more information on the actual likelihood of problems for my baby? I believe that my TSH levels were marginal, not critically low, but I can't give you the figures.
