Ok, I'm going to be a bit blunt since you asked; if this offends you (or anyone else) I'm sorry.
*You are 23
*have CF but are healthy and claim to not take any of the meds most adults w/CF do
*You haven't thought about having kids, yet someone agreed to test your boyfriend for CF (who paid for the test as insurance would not).
*you express a belief you are not 'broken', but appear to have little or no clue how to go about getting pregnant
Based upon this, it is my clear opinion that there are some major gaps in story and in your process to decide to have a child.
To get pregnant, you would need to see both your CF doctor and then a specialist called a reproductive endocrinologist. They could assist you in determining if pregancy is a possible and advisable.
In the meantime, I would strongly suggest you spend some time thinking about how this works. You are 23 and single with a disease that shortens life to the 30's regularly. Who is going to raise your child if you don't see 45? As your health declines, who will care for you & your child if you don't intend to marry?
Raising a child is not like buying a car, especially given the special aspects of CF. Please step back and think some about what you are even considering before bringing a life into this world...
Just want to say one last thing, I know that these are questions the mom's with CF on this board agonize over before deciding to carry a child so don't think they are unreasonable.
