Colace is just a stool softener, it won't make you go. Try Metamucil capsules and drink LOTS of water with them. Worked for me and I was constipated bad.
have you already delivered? if you have the prunes get into your milk so you shouldn't eat them if you are breastfeeding. just walking around in the room or down the hall is fine I just thought you should know I get cramps from prunes but I still eat them because it's better then being constipated.
