I am 38 and have CF.. Diagnosed at 3 years old. Was always really sick as a child told I could never have kids...told I wouldn't live to see 12, then 16, 18,21,25,etc. Had a baby naturally conceived at 34, had baby at 35. My advice...don't stress about getting pregnant or it won't happen. Make sure your nutrition is good and lung function is at least 70%. Drink lots of water all the time. That will help. It helps if you have normal periods. If you are working hard and stressing out about work you probably won't get pregnant just stay healthy and drink the water and don't worry about it. If it is meant to be it will happen. I won't lie to you and tell you it is easy to be a mom with CF. It is not you will need a support system in a big way. My child is very healthy and quite the little guy a true blessing. Another CF friend, 30 years is 6 months pregnant and doing well. Lost one friend 6 months after she had her baby but her lung function was under 70% when she got pregnant. Feel free to email me back
