Jen, on the whole your TSH looks ok, but it is definitely on the low end of the scale - and it's a WIDE scale.... You might want to try a very slight reduction in your doseage to try and drop your T4 (and increase TSH) a little to see if that makes a difference. ESpecially if you're having hyperthyroid symptoms - like shaking, trouble sleeping, palpatations.... It takes at least 2 weeks for a change in doseage to have a full effect on your blood levels - My specialist waits 6 weeks before testing to check the new levels. What dose are you on now? Just tread very lightly if you change doseages. And get a follow-up test around a month later.
For eg, I'm on 100mcg. My T4 was a little high, so I tried skipping one pill a week - lowering my weekly dose from 700mcg to 600mcg. My T4 dropped a fair bit so I ended up going back to 100mcg per day cause it was a bit of a hassle. I think I'm quite sensitive to it as I have a very low dose (for total replacement) and small changes in dose have a big effect.

Hope the sling goes well Hoobly - I was thinking of buying one for the next baby. Never occurred to me to make one. I spose they're pretty simple things, though. Where do you get the ring?
