Mosaic

Any of you guys have a mosaic DS baby at home? I’m in high risk for that (harmony test negative - but it does not test for mosaic) with a diagnosed vsd (cardiac defect), hipoplasia of the phalanx of the 5th finger and I’m older than 40 years old... I’m freaking out and I don’t want to do amino... please I want to know your experience with that. Thank you!
