I keep hearing about how mass creates gravity but what if gravity itself had mass? Or, what if dark matter IS gravity?
-not a high level physist but i DO think about these things!

The gravitron, that is the conductive particle of gravity, has no mass.

You just asked a mouthful.
Before I even start answering this question, let me just tell you this: everything you're learned is wrong.
As you travel faster, you gain mass automatically just because of your speed.
As you travel faster, time slows down.
It is impossible to know your position and velocity with exact precision at the exact same time.
I cannot tell you a particle's position, I can only tell you the probability that it's here or there.
Overall: once you analyze things at the subatomic level, science starts to get creepy, and all those fancy models with fancy pictures that you learned in school start to become more and more inaccurate.
WITH THAT BEING SAID:
There is a theory. It's part of science's greater goal to explain gravity, electromagnetism, and nuclear force as siblings that come from one greater force. This efforct is called the Grand Unified Theory. Part of this states that gravity is caused by particles called gravitrons. Particles have mass, so that would cause a yes.
On the other hand, Einstein's theory of general relativity states that gravity is NOT a force. It's merely a bending and warping of space around a mass that caused objects to come closer to that mass. i.e. Just by you existing, you're causing the space around you to bend and morph into a circular shape. According to Einstein, that's all that gravity is.
I don't even know what string theory says about this...
LONG STORY SHORT: if you wanna live an easy life, then the answer's no. If you wanna be a high-level physicist and think about stuff that would make your head explode, then throw away your social life and answer yes.

If gravity itself had mass, then gravity should be making itself heavier all of the time in a positive feedback loop (more gravity makes more mass, which makes more gravity, which makes more mass, and so on), until everything collapsed into black holes all over the universe.
So, my guess would be no.

Gravity does not have mass. Mass effects the pull of gravity but gravity itself has no mass.

It's like asking "Does luster has light?" Things shine because of light, even though they don't have 'light' of their own. Similarly, gravity is not an entity. It is a property, a virtue characteristic of mass. Mass can have gravity. It's not the other way round.

Gravity is normally defined as the force of attraction with which it holds objects and force doesn't have any mass in it.

gravity is a force.. it can't have mass.
Force is different from mass

think about it.
gravity is a force.
force = mass X acceleration.
gravity cannot have a mass.

It can't have mass; it has infinite range and travels at the speed of light.
