Sometimes post c section it can take some time for the organs to settle down. However that's generally just a few days.Are you eating enough fruits vegetables and whole grains as well as drinking plenty of water ? Ensure that you have some stools softening foods like papaya pear raisins prunes etc for a few days to help.

I had the same problem, I use to drink plenty of warm water all the time I feel thirsty. even I had a c section delivery on oct 23rd. now its normal.
