Fet advice

Hi everyone,

I am waiting for my period to start FET next week. I am on hydroxychloroquine I have palindromic rheumatism and sacroiliitis. I have done all blood test to see if there is any autoimmune disease and all come back normal.

Any tips/advice, vitamins I should be taking apart from folic acid and Vitamin D?

My fresh failed cycle was in September with a grade one 7 cells day 3 embryo and only have one embryo left which is 5BB hope it thaws ok for FET.

Thank you everyone.
