Took glycerin suppository yesterday,had bm. today no urge to go.....normal?

Could be: If you emptied effectively you may not have had any more move down into position for emptying.If this is a recurring problem, something like Miralax (polyethylene glycol) taken daily for a few weeks can soften/move things along enough to get and stay regular. You can then drop to using it half dose for a while then stop.In spite of its name, it's more of a moisture retainer than a laxative.
