I'll tell you what I took. I tested positive for ANAs after 6 negative cycles. Then I took:
15 mg prednisone, 5 mg folic acid, B6 and B12 (though those were for the MTHFR), antibiotics for 3 days before transfer and 3 days post transfer (though that was for the chlamydia they suspected was high in my uterus ... all tests were always negative but I had antibodies in my blood), daily shots of fragmin (a kind of heparin), fish oil, and, after the next cycle resulted in a m/c, over-the-counter bovine colustrum and 2 injections of Granocyte (one 2 hours before transfer and one 24 hours later). This was all on the advice of a reproductive immunologist.
(Note: I'm not in the US, so some things might be different.)
Best of luck to you.
