I'm currently 21 weeks pregnant. At 18 weeks I went to the doctor due to extreme tiredness, like nothing I'd ever felt before. After some persuasion, my GP agreed to run a blood test, and last week I received a call to say my thyroid levels were 'a bit off'. It seems that I'm subclinical hypothyroid with anti-thyroid antibodies present. I've been prescribed levothyroxine (25mg) and am due to see a consultant in around 4-5 weeks time.
From the brief explanation I was given by my GP, and from what I've read online, it seems that hypothyroidism can lead to severe complications in pregnancy (preterm birth, still birth, pre-eclampsia, placental abruption etc.) and also to fetal developmental defects and intellectual impairment in the child.
So obviously I'm now pretty worried! Does anyone have any knowledge or experience of hypothyroidism in pregnancy and might be able to put my mind at rest?
For reference, my levels are:
TSH: 5.23 mU/L (above reference limit of 0.54-4.25)
FT3: 3.7 mU/L (within reference limit of 3.5-6.2)
FT4: 10.0 mU/L (within reference limit of 8.0-16.0)
TPO antibody: 671 (above reference limit of 0-8.0)
