Our son with CF showed echogenic bowel at about 22 weeks when I went in for a level 2 ultrasound for a different issue. We declined an amnio and my husband and I were sent for carrier testing which obviously came back positive. My care was then transferred to a perinatologist who did ultrasounds every month. Near the end of the pregnancy I was having stress tests and ultrasounds weekly. They wanted to keep a close eye on his bowels and make sure that they didn't burst and that he wasn't in distress.
