I had had a history of blood sugar problems (in response to certain medications) and so my docs thought surely I'd have gestational diabetes and that that might turn into cfrd, but I never had a single problem during my pregnancy with my sugars - and they were monitored closely. I stopped all the medications I could do without - for me that was anti-depressants, prilosec and TOBI. I was pretty miserable without the prilosec even when they put me on an alternative, so as soon as I passed the mid-way point and they felt it was safe, I got back on it. I kept taking my enzymes and albuterol nebs. A really great resource for fetal/nursing baby safety of medications is La Leche League. Even if you're not or don't plan to nurse, they still can be very helpful in obtaining accurate, up-to-date info related to pregnancy. I found that the biggest concerns I had for my baby's safety was in determining which diagnostic tests I could do without and making sure I gained enough weight and took in a well-balanced diet. Now knowing (I didn't then) that ultrasounds are not proven safe, I would have declined most. Docs may try to push amniocentesis or chorionic villus sampling on us more than others because of the chances of CF for our babies, but these are much more risky procedures that have much higher risks for causing premature labor and fetal death as well as infection to the mother. I would advise anyone thinking of getting pregnant (even farther down the road) to begin learning about alternative medicine and wellness. There's so much risk to antibiotics, but there are so many other effective ways of treating problems and infections. More cities and areas are offering birth networks or have midwives and even if you don't choose an alternative method of birth, these are good resources for alternative methods of care. I would also encourage women not to rule out an alternative mothod of giving birth. Out-of-hospital births have a much lower rate of complications for both mother and baby and many areas offer nurse-midwife/physician staffed birth centers that are good alternatives for people who have CF, but whose pregnancies are healthy and uncomplicated. That's my 2 (maybe more) cents. Hope it helps. HollyCatherynPS - I had my baby at home with a midwife and it was GREAT!
