Genetic testing

Anna • Baby boy born in Dec 2018💙

I am 13w4d today. I had blood tests done a couple weeks ago. The doctor called me and told me i tested positive for cystic fibrosis? I wasn’t aware that I am a carrier for it but apparently in order for the baby to have it, the father also has to test positive as well? The babies dad says hes pretty sure hes a carrier as well because his sister is? My question is should I be worried? 😬😢🤮
