I had the same issues with my first 2. With my youngest I took alfalfa and royal jelly through out my preg. and in the end I drank red rasp. leaf tea. he not only didn't need treatment, but his billi came out a 2 or 3 when they tested him (they thought he looked yellow). My older two were 17 and 19.5 or 20 at their highest.
NOW, not saying I think you ought to go out and try that, do your research and decide for yourself if this is the right path to go. I have since learned that since I am predispositioned to have hypothyroid that I should have avoided the alfalfa, but I think it still was worth it, since my youngest was/is the healthiest of the 3.
Ahhh tea the essence of life.
