Spina bifida

Has anyone else gotten a call from their doctor after your second set of genetic testing saying that your baby was at risk for this? 
I did today and they told me not to freak out because they see negative tests often and nothing is wrong. I have to see a specialist and have an ultrasound to see if they can see anything on the baby's spine. We haven't even had our anatomy scan yet. I can even feel the baby moving all the time. Heart beat and everything else have been great. 
I'm just looking for some comfort... My husband and mother in law are both saying everything will be okay.
