Re: Pregnancy with hypothyroidism!
Most definitely, a successful pregnancy requires thyroid hormone levels (FT4, FT3) to be towards the upper third of the range.
Since it can take 6 wks. for a synthroid/levothyroxine dose adjustment to reflect in levels, you really need to stay ahead of the game with your dosing.
I agree that you need to take a peek at your levels and make sure your treatment is optimal.
