I forgot to tell that in the end they actually did an ultrasound before I was to deliver and they showed stuff floating around in the amniotic fluid. They did an amniocintesis (sp) and it was yellow. Anyways what they came to find out was that there very well was a blockage that worked itself out and that is what was floating around.
With our oldest we did have to go through the surgery for meconium elias (sp). I would just try to enjoy your pregnancy as much as you can and know that you have a great community here that will help you through whatever happens. You get through it and it starts to begin the parents being strong for their CF child(ren) for the future.
