Can anyone advise me on TTC with an underactive thyroid?

I have an underactive thyroid; it became that way after having DS 3 years ago. I've been on 75mcg a day thyroxine. My levels at the mo are 4.6.

I was told by another Mum with similar probs that to conceive the levels need to be between 1 and 2. When I asked my doctor last week they confirmed this and told me to up my dose to 100mcg a day. Wish they'd bloody said that when I asked them at my last appt 6 months ago! I asked back then if an underactive thyroid would cause any probs with conceiving, and they said "No, not as long as it's treated". Now I thought I WAS treated as I was taking the tablets, and they were telling me my levels were within the normal range. Why didn't they say 6 months ago that the optimum levels for conceiving are between 1 and 2?! I could've started upping my dose 6 months ago and would probably be at 1 or 2 now, instead I've got a good few months to wait now before the higher dose takes effect and my levels get to 1 or 2.

And I'm bloody ancient, so I haven't got all the time in the world to wait, GRRR!!!

Anyway, if anyone has any tips or advice I'd be very interested in hearing them as I'm surely not getting great advice off the doctors. One question of mine which they wouldn't answer was "Is it actually dangerous to TTC while my levels are at 4.6; should I wait till they're down to between 1 and 2 before trying?
Or is it just that it'd be DIFFICULT to concieve whilst at 4.6, but still worth trying?".

I just don't know whether or not to let DH near me!

It varies from person to person and the docs have no definite answers

TSH too high and you won't conceive or you will conceive and miscarry. But then you could miscarry anyway for other reasons

I would expect your TSH to have changed by around 6 weeks
I would try anyway

Sorry if this isn't much help
