Stay hopeful, I am allergic to sulfur drugs, I was 29 also on methotrexate and after a year my gyne gave me a pill called clomid two months on and surprise I was pregnant. Something I was checked for was an autoimmune disorder called antiphospholipid syndrome, it causes spontaneous abortions usually before you even realize you are with child. Since you suffer from the RA (autoimmune disorder) it could'nt hurt to get checked. good luck, mommy to be.

My x husband and I tried for 2 years after my miscarriage. We had my oldest already. I never thought I would get pregnant. I didnt even think about it after we got divorced. And one day out of no where 4 years after trying, my youngest was concieved. My mom and grandma told me it was because I wasnt trying to so hard. So when your not expecting anything, expect the unexcpected. Good luck and dont stress! it will happen when the time is right!
