Genetic Carrier Testing for SMA

I'm scared. I'm 15wk+6 and received a call today about the genetic carrier screening blood test I had done. They told me that the baby's father should get screening and genetic counseling for Spinal Muscular atrophy. She told me it was really common and that just because one of us is a carrier doesn't mean that the baby would have it. Does anyone have experience with this? Can someone give me some wisdom or comforting words? As I said before, I'm terrified and this is my first baby.

It means a lot, thank you all.
