You're saying that you have few BM's a day. That is very good but that might be the reason for your cramping throughout a day. Your large fiber intake makes everything move around and that gives you pain. Maybe if you take just a little less fiber (but you will have less BM's), you might get less cramping.
In my case, I get pains if I eat something I shouldn't have had. That is just a sign for me. But it's not a cramp, but more of a sharp, stabbing pain. I only get cramps before BM's. I have a few BM's in the moring, 1 right after another. It's weird, but that is my routine now.
I don't know if I answered your question.
Thanks.
