Re: Pregnant, Hypothyroid, What Do I Do Now?
TSH should be disregarded completely when taking Armour, NP, Erfa, or other natural thyroid. TSH naturally becomes suppressed due to the T3 in the med. My own TSH hasn't been higher than .02 for about 8 years now, but my MD understands that it doesn't matter, as long as the FTs aren't excessive. Any MD who prescribes natural thyroid ought to "get" that, but amazingly, some still don't.
It appears your NP shouldn't have been reduced, just some T4 added to it. I'm concerned that your FT4 is still too low to sustain a pregnancy. I would have a discussion with that doctor, telling him that you'd like to maintain your FTs at least in the upper half-to-third of their ranges. I'd ask for a restoration of the 3.5 grains NP so that your FT3 returns to where it was. You still might need as much as 112.5 mcgs of Synthroid as well, since your FT4 now still isn't where it should be.
I once won a dose increase by telling my MD that, even though my levels were within range, maybe they still weren't my "normal". He immediately agreed. I suggested another member use that argument, and it worked for her too. Couldn't hurt to try it yourself.
