Newborn Screening- NERVOUS WRECK PLEASE HELP!

Hello, I am new to this community and new to a health issue of this caliber. I guess my question for people out there is. I got a call from my doctor telling me that there is a more than likely chance my child has CF. I have two other sons who have not tested positive or even come up as a concern for CF. I have to wait for a swear test to tell if it is a yes or a no. They center is supposed to sit down with me and my husband and I have been worrying myself sick because I feel just so lost and stressed out over this whole ordeal. I just can't really get information that is completely accurate. Has anyone else been through this? Is it possible she could come up with a negative sweat test?
