I had PGD done last year. I have one child also with cf and felt the same way you did...... If I had the money I would do it again. It did work for me, but I then had a miscarriage. You just do not know how your body is going to take it. I is hard though, when the DR came back with the results, ( I had 8 eggs total) which ones were carriers, which ones had CF, and which ones did not, I felt very guilty for a while knowing what would happen to those eggs that I did not put in. It was an emotion I did not think I would react towards, but your emotions are all out a wack from the drugs. All in all , it is very expensive, a lot of dr appt, drugs, shots but in the end I would do it again. Now is the hard part. What do I do now?
