Hi, I was given a ratio of 1:149 just from the neck thickness ultrasound scan. As the ratio was very bad, the doctor recommended me to do CVS. I did the CVS and the baby was perfectly healthy. I have just delivered my baby this Oct and she is very healthy.
You may ask your doctor if invasive test is advice(there are risk that comes with it, including miscarriage..) but at least you will have a peace of mind... I do understand what you went through.
