This might be a dumb question, but for those of you who have had a c-section were they able to go through your previous abdominal incision from j-pouch surgery or did they have to make a new incision? 

Not a dumb question at all. My birth doctor checked my scars out to determine whether they could go through one of them instead of adding yet another one. Unfortunately she cannot use my old ones because of where they are placed. 

I had a low horizontal incision from my bowel surgery that they reused for the c-section. It just made the scar a little wider. It remains to be seen if they'll use it a third time.

I had the same scenario, no GI surgeon present but one on call and alerted to the date and time of my c-section.

Yes, lots of the same pains and stretching tearing feelings with both my two pregnancies.

C-Section was my decision both times, the high risk OB said I could vaginal if I wanted but 3 ladies in my group did vaginal and all three had some kind of issue. Two with new or worse leakage and one tore the pouch off the wall and had to have it reattached. Also my actual surgeon said risk for vaginal is very high but it was up to me in the end. I heeded his warning, I like and trust him the most.

No using old scars though I have 4, they made a new and larger scar though this time they say they will go through the same C-Section scar so I wont have a new one but to expect 8-12 weeks for total heal rather than the 6-8 of the first c-section.
