Hi thanks for query I am not wrong by lupus you mean SHE. So it means you have been diagnosed with SHE with RA. That makes it very interesting because traditional wisdom in rheumatology says SHE and RA are mutually exclusive diseases which means you can't have both of them at same time. Neverthless development of SHE like features have been described in RA, and it is associated with increased mortality. This raises some question in your case, and you should discuss with your doctor Which criteria was used to diagnose RA?was it older 1987 criteria? Is your lupus severe? Has kidney biopsy been done? The most common cause of abrupt cessation of menses in SHE patient would be cyclophosphamide treatment. So have you taken it? You are taking HY Chat Doctor.  Do you know it can be teratogen? I have tried my best to help you Take care
