Levels and TTC

Hi all,

My hubby and I will be trying for a baby in the new year. So I took myself off to the GP having read on NHS site and EVERYWHERE that I should get levels checked etc before I TTC.

Not only was she disinterested she also left me feeling like I was over concerned. She did agree that when I am pregnant then to be straight back in touch but my last text was feb 16 and TSH was 2.74 and normally they wouldnt check again until Feb 17.

I kind of thought that the TSH should really be lower than that when trying to get pregnant-she thought not. She did advise that I would be considered a slightly higher risk pregnancy.

What are your experiences/thoughts?

I did manage,eventually,to get a blood test now,so will take myself off for that this week.


Silly me trying to plan a pregnancy. Knowing that I would need intervention.

NICE recommendations before they were revised in April 2016 were that women attempting to conceive should have TSH in the low-normal range 0.4-2.0 with FT4 in the upper range and that Levothyroxine dose should be increased by 25-50mcg when pregnancy was confirmed. Current recommendations which you can show to your GP are:


Hi Clutter,

Am I reading the NICE guides correctly that I need to be referred to an endocrinologist?

There also doeant appear to to a numbered tange offered on there.

Does my GP have a requirement to go by NICE guidelines?

Thanks again



That's what the NICE recommendation says. The range was included in the NICE recommendations before it was revised in April 2016. There are ranges for each trimester in the other links I posted. I don't know whether your GP is required to observe the recommendations but I think most will.
