First, congratulations! On two counts: 1) being pregnant; and 2) your RA, hopefully, going into remission. I believe the research says that RA normally does go into remission during pregnancy. However, delivery may trigger a new flare. One of the reasons I don't believe I have RA (although that is my dx) is that during my twin pregnancy my joints were in terrible shape. I could hardly walk at times between my hips and my feet. Not to mention that I don't appear to have the erosive type arthritis associated with RA. I wish you the best.
