I have just started preparing for a fresh embryo transfer. I am currently on 50 micrograms a day of levothyroxine but have now started on 2mg oestrogen three times daily and cetrodide injections once daily. I think I might be dosing them too close together. How long after taking thyroxine can I take the first dose of oestrogen ( atm I am leaving 30minutes-1 hour)? I am feeling like I did before I started thyroxine- exhausted and achey so think maybe I have reduced the absorption of thyroxine. Any thoughts would be great doctors at fertility clinic didnt seem too concerned re timings of thyroxine and oestrogen.
