it's frustrating for sure - it's very difficult to find dr's even supportive of taking Armour around here, so I went on Synthyroid which did start making a difference, though my T3 is still in the low/normal range.
I went on it to see if it was a factor in my miscarriages, though I had a healthy DS untreated (though my symptoms weren't as bad then as they were when I started Synthyroid)
I knew we were TTCing and taking something was better than nothing, so I'm happy with my choice for now. Switching over the Armour while in the first tri would not be smart anyway, knowing that my body could really swing while I get the level adjusted - I'll save that for after being pregnant.
I've had one increase so far, and I really noticed a difference at 4 weeks. Like you said though, it's a little trickier closer to 7 weeks knowing what's pregnancy & what is thyroid. My TSH is a little over 2, and my FT3 is low/normal and my FT4 is mid range - so I know I'm not converting well. I'm making sure to get more selenium...my zinc supp intake is good, and my iron level is getting higher actually, so I think I'm still doing pretty good.
I think I would like to ask for a slight increase in my meds though, just to bring the TSH a little lower, the FT4 a little higher, and I don't think there is a good way to just add T3 is in the first tri? I'm still just seeing my GP, so I don't know....maybe she'll refer me to an endo after she gives me a little increase and I can ask about T3 there.
At least I know I'm getting some form of T4 for the baby, so the rest is just tweaking how it's been used. I'm much better off being treated than not, even if it's not the perfect form at the moment.
how long have you been on meds for?
Were you're levels pretty stable before getting pregnant?
Will you get your FT3 & FT4 checked too, or do they just go by TSH?
