Congratulations, Emma :)

There's absolutely no problem taking Levothyroxine during pregnancy. It's often increased by 25mcg-50mcg during the first trimester to ensure TSH is in the low normal range 0.4-2.00 which is best for baby and mother. You may need monthly blood tests for the early part of your pregnancy to check levels are right. I hope the thyroid specialist reassures you.

Congratulations Emma,

You will need to be referred to a midwife asap and ensure she knows about your Hypothyroidism, you should be under a specialist obstetric consultant with knowledge of endocrine issues, normally teamed with an endocrinologist.

Hope all went well today
