What is your diet like? Any fresh fruit or vegetables? How much water do you drink? Whatever the amount is, double or treble it. Water is THE most important substance you can put in your body.
You should absolutely be having a poop every day!

uhh.. is ketchup a fruit? i dunno i drink water sometimes i like milk. i drink so much milk. it is good for you my son. :)

Optimistically, you should be pooping daily.
Once every other day is normal, too.

Anything else, you probably are sick inside.

it's not my fault it won't come out

i cant help it ok

dairy products can lead to constipation, at least I know cheese and ice cream can

well eat lots of fruit and you will be shitting in no time.

That sounds more of an impaction.
I say see your doctor.
If it gets too bad, laxatives or enemas wont be able to cut it and they'll have to do surgery just to get it out (and you definitely don't want that to happen). Don't wait till you start vomiting out feces because it has nowhere to go...

3 times a day to once a week is all within the normal range BUT if you usually go once every two days, then this isn't normal for you.

Drink a lot of water, get stuck into the dried fruit, they do actually work and give it a day. If no luck make an appointment with your doctor. The reason i mention the above steps BEFORE going to the doctor is that if your doctor isn't crap he should be trying those things first before giving you meds. Giving prokinetic agents to people that are constipated because of dehydration, for example, is not terribly smart.

gosh I could never go 3 times a day wow I dont even pee that much a day. but I see once a week is normally.

in regard to other poster I dont want to have potty surgery.. I DONT WANT TO HAVE POTTY SURGERY

You have to put stuff in to make stuff come out. Might not be eating enough.
