help please, 9 days post op and feeling some cramping?

I am 9 days post op has not been easy but I have been following directions.  I had tomato soup about 4 hours ago and I have eaten it before.  I then had a protein drink about 2 hours ago.  I am having a small cramping feeling in my little pouch?  Is that normal?   Did I do something wrong?  When I take a drink of water I feel the crampy feeling too.  Can still ge****er down but have not felt this before and don't know if I should be worried? 

cold liquids can make you cramp. make sure your liquids are room temp. sometimes this is short tern and for others it's always.

 I am 2 1/2 weeks out, and I noticed that plain water has a tendency to give me that weird crampy, not really painful feeling too. So, yeah, make sure it's room temp or sometimes warmed fluids feel better and I do not notice anything at all. I just thought it was me, I mean, who would think plain water would do that!? Sometimes I think I feel it because my sips are too big, and so I slow it down. But if there are no other problems, I would not worry.
