TSH of 4 while TTC


Has anyone successfully conceived while having a TSH around 4 and not taking thyroid medication?

My current level was just checked, TSH 4.01, T3 & T4 both normal. Everywhere I read says that TSH while TTC should be under 2.5 or there is an increased risk of miscarriage. My obgyn told me those numbers were fine and nothing to worry about. I just had a miscarriage in March and don’t know the cause but this has been on my mind lately.

Just looking to hear of any success stories for people who did NOT take any thyroid medication before conceiving. And curious to see if you were started on it while pregnant?
