TTC with Arthritis

Please help, as the title says, we're TTC. I have rheumatoid arthritis in every joint of my body. Got diagnosed at 18months old, I'm now 34 (almost). I've had two healthy pregnancies, 10 Years ago. Since then I need two total shoulder replacements and two total hip replacements. I dream constantly about having just one more child. I don't feel like that part of my life is over yet. I've been drug free (after been on everything including methotrexate, naproxen) for 2 and a half years, choosing to manage my pain other ways, heat, resting, pressure bandages etc. However 3 weeks ago a flare came out of no where, I'm not sleeping, I constantly hurt, I'm just generally sad 🙁 Do I hope it passes and continue been drug free and TTC or do I accept that I don't need another child in my life right now and focus on myself, medication and getting better. I'm so torn. This has come out of the blue. I was doing so so well with no medication. I could finally taste food, enjoy food and my general life was looking good (by general life I mean, still in a wheelchair as my hips are bad and my partner cares for me. I thank everyone from the bottom of my heart that actually reads this to the end ❤ Lots of love x
