Thanks Jen!

I notice in the first link you give me the author refers to a 1994 study, does anyone have links to that actual study? I am very wary of presenting Mary Shomon's work to a GP because she is generally recognised as a bit of a crackpot in medical circles. I did hear one endo say to another once (not my endo, when i worked in a hospital) "Well, she's got Shomon's book so now she thinks her twisted ankle is down to her thyroid!" She's not well-regarded by many and though i don't discount her, i don't want to alienate my doctor from the word go, iykwim.

Also i see you have the link to the AACE guidelines. I'm going to bring those up, but TBH i'm not too hopeful on potential impact of that one, since the UK's new clinical guidelines state that the TSH "normal" range is 0.5-10, yes TEN!

Anyway, i got my results over the phone:
TSH: 2.76
fT4: 17.5

I didn't ask for my fT3 because the person telling me the results didn't know what the numbers meant and so i instead arranged to talk to a GP tomorrow.

I'm kind of up in the air about it now because i had kind of decided to go with the conservative TES clinical guideline which states that for pre-diagnosed hypothyroid women who plan to ttc the TSH should be kept at <2.5.

My main issues now are that a) i went for a long run and my legs (finally) didn't feel dead (which for me is a sure sign of being hypo, when my body isn't responding to training) and in fact i finished my run feeling sprightly even, and b) with levels so close to 2.5 i'm not sure i would want to mess with them and risk getting hyper (my TSH level was 16 on nothing, 4.7 on 25mcgm/day and has been 3.8, 2.95 and 2.76 on 50mcgm/day) and having to sort that out again before ttc...

I have a Mirena coil fitted and am pretty sure i'm still O'ing, though that's based on EWCM, not temping or anything. Should i temp/OPK to see if i'm Oing? Lots of people get no AF when they use Mirena but i still do. But then i got AF when hypothyroid, with a big goiter, fully BFing DD 6 weeks after she was born...

LOL...so many questions...
