Hi Ladies,
I'm extremely new to this situation...literally just found out a few hours ago...
So my doctor called and told me I'm going to start Synthroid at 25mcg because my level was 3.8 and I guess they want it more around 2 
We've been TTC #1 for a year now with no luck which is why we've started being tested for things. 
My thyroid lab is the ONLY thing that came back abnormal for my husband and myself...(they did about 17 blood test for me 🙄) 
Did anyone conceive soon after starting meds?
I know some of you have been diagnosed before you were TTC but I'm just curious if this is why we haven't gotten pregnant!
Thanks!!
