Thank you for asking the query. I don't think suppository is a good idea. The 'stuck in' feeling might not be constipation at all.
The best method to ensure adequate bowel movement in your case will be to have a fiber rich diet. This is link from Mayoclinic which could be useful for you. http://www.mayoclinic.com/health/high-fiber-foods/NU00582 (please copy paste).
The reasons I say fiber rich foods than suppository is because since you had a few bowel movements, what you now need is a 'stool forming' agent. High fiber is the best stool forming agent and this will regularise your bowel habit. You may also take a probiotic drink /tablet for a couple of days.
Hope this helps. Please feel free to ask followup question. Thank you.
