ASD Concern

Hi All, it’s my first time posting here and I just want know if anybody here has a child diagnosed with ASD? I have a three year old with ASD and am now 5 months pregnant with my second baby. I’ve read somewhere that one factor that can contribute to a child developing ASD is if he/she has a sibling who has the same condition. I’m now paranoid that my second child also be diagnosed with ASD. Especially since my first born is still undergoing therapy and is still unable to converse. ? Hoping I can get some input on this.
