Spinabifida

So my Dr called a couple days ago and told me from my screening blood work that our baby has an increased risk of having spinabifida...she said 1 in 65 chance. They bumped up my next ultra sound appt to the 16th of November when I'll be 21 weeks. We are so scared and freaking out. Dont k ow how to mske it thru the next 3 weeks!!! Anyone else have a similar situation?
