I had a baby 5 months ago, I was having painful bms w/ blood. now I go okay but always feel an urge to go Why?

You most likely developed hemorrhoids during pregnancy that bled when you had to strain, the fiber and water softened the bm's enough that you didn't have to strain so the bleeding stopped. It is likely that you need to continue with the high fiber and increased water so that you have a more complete BM, and don't feel that sensation that you didn't empty completely. If you stick with the fiber and water, and increase your exercise some and are still having problems then it will be time to consult your Dr. good luck!
