I have never known any other family members to have CF. I did find out that my paternal grandmother had twin brothers that died one day after birth. How they died I have not found out yet, but am looking into it. My maternal grandmother had a younger sister die at the age of two from asthma!!!!!! Bowel and stomach issues run in the family on both my mother and fathers side. My mothers side has IBS with the gotta go's, my dads side has IBS that can never go. I got the never go. Childhood bronchitis is rampant on both sides. Honestly, both of my parents could be carriers and I just got lucky. Other than that, I don't know much else.
I have 3 sisters (2 by my moms second marriage, 1 by my dads second marriage) also an ex brother in law (Jaelyns dads little brother). All 4 of them are in their twenties and are not necessarily trying to have kids but def at an age where it could happen. I always think if one of them will ever have a CF child like me. If they knew, would they still do it. But so far, none of my sisters or bros have been tested to see if they are carriers. It scares me sometimes for them. For their unborn children I already worry!
