I am 25 and have CF. My daughter is almost 2 1/2 and she doesn't have CF. I was in good health before I got pregnant and consulted my docs about it. I am currently studying to be a midwife. I had a very healthy pregnancy, with no sign of diabetes, even though I'd had bouts of diabetic reactions in the past (as a result of steroids). I have had no sign of diabetes since either. It took trying for a year before we got pregnant. I have learned that pregnancy is not just related to having cycles. Even if an egg actually becomes fertilized, if your body is over stressed, it may send signals out to your uterus to shut down for a while. Stress, whether physical (like illness or heavy athletic training) or emotional has a direct effect on your fertility. You may or may not have regular cycles, but either can happen without ovulation. If your body struggles regularly to get the oxygen or process calories it needs to function, it is less likely that your body with allow a pregnancy. It will determine that there is not enough oxygen, food, energy, etc. to go around and will hinder the process. The other factor in fertility for many women with CF is the thickness of cervical mucus. You can try taking an expectorant that has guafeneisin in it or taking guafeneisin alone to thin the mucus around your fertile time - which is incidentally not 2 weeks INTO your cycle, but rather 2 weeks before your next period. For a woman on a 4 week cycle this makes no difference, but if you have long or short cycles, this is important to note.Once you become pregnant, it is even more important for a woman with CF to consider carefully her nutrition. Don't waste calories on empty things. Do hydrate - at least 64 oz of water a day. If you crave tons of ice, you are probably anemic and need iron supplements. Also, educate yourself about your pregnant body, your growing child and the birth experience. Be open to alternatives. Women with CF have the special consideration that they may get sick and need treatment. Conventional antibiotics may not be safe for your growing baby, so you need to be as educated BEFORE hand about alternatives (even for some of your routine meds - like Prilosec, which is contraindicated through the 2nd trimester). Chiropracters, naturopaths, homeopaths, midwives and acupuncturists are all good sources in starting your search. Hope a bit of that is helpful.
