Hypothyroidism and TTC

Jenna • Bonus mom to two 👨‍👩‍👧‍👦 Expecting my very own on Jan 27 ❤️

I have been on 50 mcg of Synthroid for one month and my TSH numbers went from 4.89 to 4.24. Doc is upping the meds to 75 mcg, but I’m not sure what to expect. My primary and online says I should be around 1 TSH, but OB is saying I’m still within normal range to conceive. Anyone dealt with this?
