I was diagnosed 1 1/2 years ago with graves and opted for radioactive iodine therapy. it was successful and now I'm on synthroid working towards optimal levels. new labs should come in tomorrow and I am hoping for close to optimal, I am on 175mg levothyroxine currently. We have been ttc passively since January but I was warned that non optimal labs would mean it's unlikely we would have any success. has anyone had success ttc with close to optimal labs on synthroid? everything I find online says it will possibly take years which is frustrating as we want to start our family soon.
