I took one Dulcolax laxative & a few Dulcolax stool softeners. I had normal BM few hours after. Can Dulcolax cause painful cramping? Very strong

Probably, since... Dulcolax (bisacodyl) is a stimulant laxative that works by increasing movement of intestines, helping stool to come out, assuming normal GI anatomy without inflammation, stenosis, extrinsic or instrinsic obstruction. Cramping would be a common side effect, but if persistent please seek evaluation.
