How do autoimmune disease affect fertility and pregnancy?

I would like to start trying for a little one next year. I enjoy chronic erticaria and raynauds, and I have be tested for lupus twice and recieved a low positive result. I am really worried.

I haven't spoken to my GP about it nonetheless but will soon. I just want some more opinion. Especialy from people within similar positions

I have MS - for a psychotic moment a couple years ago I thought I considered necessary to have a child (I got over it pretty nifty - but still) I spoke with my neurologist and my GP - both of them said have a baby shouldn't be a problem.

Definitely yak to your doctor - sometimes the issue isn't "can I get pregnant - it's should I achieve pregnant."

Your doctor can best help you answer that query.
