Darn Thyroid

So my blood work for my TSH levels came back today to the Drs. office. It's up a little bit. The level is 6.14 and my OB wants it to be down around 2.5-3. So I've got to adjust my meds. Am I going to have to go through this throughout my pregnancy? Hope not! But I guess it could be way worse. I'll adjust now and test again in 4 weeks to see that it's getting down there.
