Going for a cvs

Natalie
So my nt scan came back high for many chromosome abnormalities . So I'm booked in for a cvs on 21st Oct I'm am so so nervous. A CVS is a needle into the belly to the placenta and it gets a biopsy to see what complications the baby may or may not have . So so nervous about this as 1% chance of causing a miscarriage. Has anyone else had this procedure ? Xxx
