ASD parents being judged

So this is strange to write but I'm so mad I'm speechless and almost beyond mad if that makes sense. My partner of 16 years has always had certain traits and qualities associated with ASD, or what would have been called Asperger's. We have openly joked about it and have acknowledged it's part in our disagreements. More recently as female ASD has been spoken about we have started to realise my traits don't all fit with my dyslexia diagnosis and it's more likely I am ASD as well. I was formally diagnosed 18 months ago. Anyway we finally got pregnant after spending years making sure we were as ready as we could be. Today a co-worker (I work within education and the co-worker works within additional support) said she just couldn't understand how someone with ASD would even consider having a child knowing they were going to have no life............ I walked away, she knows I have a diagnosis and am pregnant.

I'm speechless what could or should I have said?
