RA and Pregnancy

I'm a newbie to this site. I'm in hopes to find support from others that know what I'm going through? Has anyone heard of problems with Female RA patients in conceiving. To the fact that, our immune systems are so low and constantly fighting this disease that our bodies tend to miscarry. I miscarried three years ago and I was told that's what offset of my RA.  Anybody with any information on RA and Pregnancy? I want to know more besides the 70% to 80% women go into remssion when pregnant I already know that(actually that's about all I can find). I haven't been able to find hardly any information on this subject?

Thank You & Peace, TMichel
