Hypothyroid and 7 weeks pregnant

[Stary]

Just had a 7 week scan which showed a twin pregnancy. I have been advised to organise a referral to a endocrine-ante natal clinic which is proving challenging- apparently it may take 6 weeks. The fertility clinic have advised me to double dose of thyroxine two days a week. Does this sound ok for the whole of the first trimester there is currently no plans to repeat thyroid function tests. Am i just stressing over nothing or do I need to do anything else as 6 weeks seems a long time to wait before any further action. Thanks

Congratulations, Stary!

Do you know what your thyroid results and ranges are? TSH needs to be in the low-normal range 0.4 - 2.5.

NICE recommends increasing dose by 30%-50% when pregnancy is confirmed to ensure good foetal development. cks.nice.org.uk/hypothyroid...

Management of primary hypothyroidism: statement by the British Thyroid Association Executive Committee

13. The serum TSH reference range in pregnancy is 0·4–2·5 mU/l in the first trimester and 0·4–3·0 mU/l in the second and third trimesters or should be based on the trimester-specific reference range for the population if available. These reference ranges should be achieved where possible with appropriate doses of L-T4 preconception and most importantly in the first trimester (1/++0). L-T4/L-T3 combination therapy is not recommended in pregnancy (1/+00).

Last tsh was 1.87 in october so hopefully still ok but would like reassurance from gp or referral that this is ok and shouldnt need to increase more for the first trimester :s
