Recently diagnosed sub clinical thyroid

It's not just about TSH but also your T4 level.. your dose should be increased in pregnancy if you've been on the same dose and it was controlled but maybe you've been on it for a short period of time so they don't want to rush and increase it?? You should be referred to a consultant and they should be seeing you with your dating scan. Don't worry about the risk of miscarriage you're already on the tablet and your levels are getting better.

I was diagnosed during pregnancy (around 9/10 weeks I think) and put under the care of an endocrinologist at the hospital where I was due to have the baby. It might have been because I wasn’t on levothyroxine previously but they were keen to monitor and reduce it down and I had a blood test every 6 weeks and a telephone consult each time. By the end of my pregnancy I was on 125 levothyroxine. TSH was 6.8 and t4 normal at the start. I get the worry as I had it too and was around 20 weeks before my tsh went within the normal range and I now have a healthy boy who’s about to turn 1. The only thing I wish someone warned me about was how hard postpartum would be trying to rebalance my thyroid and it was only around 9 months postpartum that it went to normal again having swung between over and under active with the medical professionals saying that my symptoms were just normal postpartum when actually it was my thyroid. Wishing you all the best for your pregnancy.
