It is unhealthy not poop.
Poop is meant to be expelled from the body on a somewhat regular basis. Normal can range from 1-3 times per week to 1-3 times per day. Everybody is different to some degree, but regardless of what is considered "normal" for you, nobody can hold poop in the body for more than a week without developing potentially serious health problems.
Without knowing anything about your diet, I can only suggest that you make sure that you are getting plenty of fiber and drinking at least eight glasses of water each day. And you might consider getting a calendar so that you can keep track of how many days have actually passed.
Not unless you live somewhere where pooping services and facilities are on pay-as-you-use basis.
On upper class poops, you must be a serious vegetarian (Herbivore)
