Congrats with this next adventure. After I had my J pouch 20+ years ago, I too was informed by the surgeon, that yes the pouch wouldn't prevent me from future pregnancy's, but he felt that with the J-pouch, I would have to consider a C section. But again.. my J pouch was done more then 20 years ago, so I'm sure they have made many positive advances with this procedure.
Putting your question out there at this site, is going to be a great resource for you with connecting to other's who went through pregnancy's and deliveries after J-Pouch surgery.
Back when I had my surgery there was no site like this to connect with others. While in the hospital waiting for my surgery, my doctor gave me a list of over 300 J- pouch patients and informed me that he wanted me to make calls and connect with some of his former patients. He felt the importance of direct contact with patients who had gone through the procedure and with answering any of my questions and concerns. I do remember it was very uncomfortable for me to make those personal calls, but those who answered were wonderful. Many years after my surgery, I too was the receiver of many calls from new patients with many questions.
This has been a wonderful site that circles the wagons for it's members for J-Pouch questions & answers.
Good Luck! Claudia
