TSH 6.5 and 10 weeks pregnant - worried!

[sazino]

I am hoping that you can put my mind at ease!  This is my first pregnancy, and I have been regulated Hypothyroid for 10 years (I am now 28).  My husband and I, thankfully, had no problems conceiving.  When my TSH was first tested post-conception at 5 weeks pregnant, it was 11.2.  My doctor immediately increased my Synthroid from .50mg to .75mg.  Now, 5 weeks later, at 10 weeks gestation, my TSH was tested again, and is still high at 6.5.  I have not heard yet what my Doctor wants to increase my Synthroid too, but I am just worried that my baby has not had sufficient thyroid hormone for development during the first trimester.  Should I be overly concerned, and demand to see an Endocrinologist?  Or is my doctor taking the right approach by testing every 5-6 weeks and adjusting accordingly?  Any reassurance would be greatly appreciated, because now I am just worried that my baby is going to have significant developmental delays because of this.  Thanks.

Thank you thank you thank you.  I can breathe a sigh of relief, as I am glad to hear the term 'low-risk.'  My doctor did increase me to 100mcg, so hopefully that will do the trick to get me into the ideal range.  Thanks again.

This is low risk with these TSH levels, but ideally the TSH should be in the 0.3-2.0 range during pregnancy.  We test every 5 weeks usually and with this scenario would increase to 100mcg.  Your doctor is on the right track.
