If you have constipation and cannot go..I HIGHLY suggest a natural herbal tea like the one above.
Go to a store like Better Nutrition, Trader Joes, or Whole Foods (usually a health food store or an organic store) and look at their teas. They are called different names like 'get Regular Tea' or 'Smooth Move' tea. The one brand I have is a brand called Yogi tea. You are looking for ingredients such a senna, peppermint, etc. I heard some teas work and some don't. This one does! Slight cramping but not too bad.
Or better yet, look at [removed] I just found the website! wb and let me know what you found
