Congratulations! I have CF, but wasn't actually diagnosed until after I had my twins. But I have always had chronic respiratory issues along with a bronchiectasis diagnosis (which finally led to a CF diagnosis). Anyway, I too, was pretty anxious about having twins...would they be healthy, would I stay healthy, would I gain enough weight, would I be able to nurse. I was extremely fortunate that I had an amazing outcome, and actually felt very good (albeit ️crazy tired!) during my pregnancy and during the first year of breast feeding. I gained weight easily while pregnant, but had a hard time maintaining my weight while nursing and my health did suffer a bit. It's an amazing, exhausting experience, please feel free to message me with any questions or concerns. I wish you all the best with your journey! Btw my twin boys are now 10!
