This is pretty normal, except maybe the stomach cramps unless they're just wind too. Also mucous farts, as my oncologist referred to them, and loss of the sense of solid, liquid or gas waiting to come out.
The sense you need to do something when you don't is called Tenesmus. It's important you don't try forcing as this increases the chances of rectal bleeding, which is also common.
Another one is loss of independent control of #1's and #2's, which might come as a surprise if you unexpectedly do a #2 while you were only expecting to do a #1.
These all usually sort themselves out afterwards.
