Blighted ovum & Thickened Nuchal fold

My first pregnancy in 2016 was blighted ovum. 2020, I got pregnant again but at 23 weeks while doing CAS, my obgyn detected thickened Nuchal fold. Apart from that, everything is okay. No other abnormalities detected. I am now starting to question myself. May issue kaya ang chromosones ko? Ako kaya ang may problema or si Hubby. I work in a call center, and laging puyat While si Hubby, techie sya. He spends more time on PC and Mobile phones. lagi ding puyat due. Can it cause chromosonal issues? #firstbaby #advicepls #theasianparentph
