If you ask this question in the parents and family section or even in the adult forum you may get more answers because I know alot of people on this site pay for them for their children. Also sometimes insurance will cover it.
Are you pregnant now? or Planning? I just noticed your age and thought it was young to be thinking of kids is why I ask. It never hurts to be prepared and all and I am not trying to knock you, it just surprised me is all.
For me insurance paid it, but I have CF. You could also talk to your gynocologist (I am assuming that if you are talking about having kids that you haev a gynocologist - if not you should get one <img src="i/expressions/face-icon-small-smile.gif" border="0">) about getting a blood screening through Ambry (from what I have heard it is the best and most comprehensive genetic testing). You may want to ask her/him especially since you are concerned about it for pregnancy issues and such. They might be able to tell you if your insurance would cover it - I DOUBT our government will pay for it in the States - but insurance might. Also to add insurance might not cover all of it but may cover a portion - especially if the two of you were married and shared insurance or something like that. I am not advocating marriage but just a thought for down the road stuff.
Good Luck,
