High Risk😟😟

I had my anatomy scan yesterday and my doctor called today and said she looked at my babes intestines and think she may be at risk for cystic fibrosis. She's sending me to a high risk specialist that can monitor the baby and do a better in depth ultrasound on her. I tested negative for cystic fibrosis but she did more bloodwork on me today. This is my first and I'm kind of scared. She seemed so happy yesterday and active. How do you manage news like this and be positive until you get for sure results?? Has anyone's baby had/have this and everything be okay?
