Cystic fibrosis and pregnancy

I'm 24 years old with cystic fibrosis. I've been in a serious relationship for 2 years now but lately I've been having major baby fever. If you know anything about CF, one issue is possible difficulty conceiving or infertility. It scares the crap out of me! Do you or anyone you know have children and have CF? I just want to see what others like me have dealt with.
