Spina bifida 20w Scan

Our baby is 20w now and we went for a gender scan. To our surprise, there’s more to it, doctor diagnosed that my baby girl have spina bifida. There’s an extra white spot captured during the ultrasound. Doctor plan for next checkup in 2 weeks time. We got really devastated by that news and would like to seek any idea in what else could we do to remedy it. Is there anyone that faced this issue and was told that it was a false positive before?
