Im so sorry to hear what you have been through/ are currently going through. I'm new to this thread and also have high thyroid antibodies, I have had two previous miscarriages and believe I'm at the beginning of a third so don't have a personal positive story however I did come across this perhaps hopeful study
The study was performed on people with no other issues other than high thyroid antibodies (abnormal anti-TPO levels) however perhaps combined with Dr M's protocol it may be beneficial? It's a study on the use of Levothyroxine in women who have recurrent pregnancy loss.
The results indicated that with treatment of Levothyroxine (amount varied to how high the levels were) in these women resulted in an 82.85% success in pregnancy and the thyroid antobodies decreased) I'm on Thyroxocine as previously prescribed by FS but have not yet been on it 2 months to know if it has lowered the antibodies and only have the lowest dose every second day. I have to monitor my thyroid levels to make sure they don't go overactive as the levels themselves are actually normal so that would be one concern, but otherwise might be an option? or are you already on Thyroxocine? Are your thyroid levels normal and you just have the antibodies or are they under active as well? Sorry if I'm being intrudsive, You don't have to answer if you don't want to!
