23 weeks pregnant and TSH T4 levels are wonky

Hello,

I was wondering if anyone had a similar issue with their TSH and T4 when they were pregnant?

My TSH is reading 2.82 (normal range in second trimester: 0.55-2.73). And my T4 is reading 14.4 mcg/dL (normal range being: 5.1 - 11.9 mcg/dL).

I've been advised to take an extra thyroid dose once a week (I've been taking 137mcg since my thyroidectomy with no med changes). This is the first time my blood test results have been wonky since pregnancy. Just wanted some reassurance about the situation!

Thanks
