I'm 28 and had my daughter 3 yrs ago, and we are planning on having another baby very soon.
My hubby and I were always open to either pregnancy or adoption, but its turned out that pregnancy has been ok for me.
However that varies with each woman with cf. Some choose adoption or other means to have a baby, some women can handle 3 pregnancies, some only 1 pregnancy. Each situation is different and all options should be openly discussed with your docs.
My Cf doctor once said that she never had a patient that had the desire to to have a family-and through one means or another-were not able to have one. I've never forgotten that.
When my husband and I were engaged, the docs told him (10 yrs ago) that I'd likely never be able to carry a pregnancy safely. But he loved me for me, and we were determined to make a family in another way if needed. Through improvements in Cf treatment, and knowledge, it turned out we could get pregnant. So things change and knowledge is power!
