I would be the same 98% chance bubs is fine? I would run with it. I had an NT last time, but not this time. I found it more stressful than it was worth tbh and was a bit put off. I guess being realistic what you need to discuss with your partner/SO whatever is what would you do if they do confirm it, as they cant tell you how severe it will be, my mother worked with disabled children her whole teaching career there is a massive range of being affected from hardly noticeable to super severe. I would'nt worry too much. 98% is pretty exellent. I swear these scans create more stress than is needed during pregnancy
