Hi there. I haven't been on this site in a very long time and I posed a similar question a few years ago. I am happy to report I was able to get pregnant, grow, and deliver a healthy baby boy. He is 3 years old now and the light of my life! I was followed very closely by my obstetrician, but I was lucky and did not need to be followed by any high risk doctors. After my 20 week scan, they were able to tell me my son's anatomy was all normal. Starting at 28 weeks, they did serial growth scans to be sure he continued to grow at the expected rate. Pregnancy is very nerve-wracking and I didn't go through without any anxiety, but my pregnancy was very uncomplicated. I echo the sentiment above - it's all in the hands of someone or something larger than us. It's hard to tell you what you should or should not worry about, as everyone's experience is different. Having CDH just puts us in a different category. Good luck! Please let me know if you have any specific questions!!
