Possible cf

Hi everyone my story is a bit complicated. Im 23 years old and when I was 18 I was given a genetic test for CF and it came back negative the reason my Gastro dr ordered it was because of acid reflux, elevated lipase levels and sludge in my gallbladder which since then has been removed. Just recently my new gastro dr told me about the possibility of CF. I only have one person on my dads side that has CF no one on my moms. I don't have the typical CF symptoms just occasional unexplained shortness of breath, frequent respiratory infections severe acid reflux and persistent low vitamin d levels. My gastro dr said that I could have a rare mutation that wasnt checked for when I had the gentic testing 6 years ago and I haven't been sent for a sweat test. I remember asking the gentic specialist to repeat the test and she told me the test is pretty accurate. Im at loss here I don't think I have CF but it would explain a lot of my problems and reading other people's stories and how they were diagnosed later in life it's made me question it even more What do you all think?
