To ask a doctor, go to the forums page and on the right hand side are all the ask a doctor forums. I think the arthritis ask a doctor forum would be the right one for you.
Regarding Lupus, it is an autoimmune disease that, depending on which form you have, can attack the skin, joints and/or organs. It has periods of flare and remission just like RA and is treated with some common meds.
Most of the time, women with Lupus have the same chance of conceiving as the rest of the population, but there are exceptions and a condition. The exceptions are women who have been treated with cytoxan and women with a clotting condition called antiphospholipid syndrome. The condition is that the Lupus should be in remission for at least 6 months before trying to conceive.
