Genetic disabilities


I’m 22 weeks pregnant today, I have a 7 year old with my ex and a 1 year old with the same guy I’m pregnant with now. My 1 year old got diagnosed with epilepsy that has progressively gotten worse and she now has high chances of heart failure and/or sudden cardiac death... so I haven’t been really feeling this baby move and my ob doesn’t seem concerned but I’m so so worried.. all of the problems my 1 year old has had determined to be genetics on the genetic testing we did, so this baby has high chances of something going wrong, I’m trying to think positively but I’m so worried for my babies and the outcome of this.. anyone have similar stories or any advice maybe.
