So i have a Arduino Uno R3 plugged in and powered via USB.
I am using the example "Blink" program, and it seems to upload fine.
But the problem is that it isn't blinking consistently. its not 1 second on, 1 second off. Its more like 3 quick blinks and then a second of pause.
Any ideas?

That 3 flash burst sounds like the bootloader's indicator. If that is repeating, then it sounds like the UNO is rebooting repeatedly.
If it's just 3 quick flashes before it settles down to a regular 1 second flashing, then that is fine.
Well i see the bootloader blinking. Thats really fast, much faster than what the program seems to be doing.
Is there a possibility that these LED's are designed to blink when put into HIGH (voltage)? As opposed to just staying on in the HIGH state?
Could be, hook it up to a resistor and battery to test. I have some that change colour so they must have some sort of circuit inside, so there surely would be flashing LED's available.

Are you using the on board led13? What leds are you using? If you have changed the code from the example, post the code.

If you are hooking up an external LED, it is possible they are designed to flash. (You wouldn't be the first one caught by this.) If you attach the LED to Pin 13, does the on-board LED and your external LED act the same way?
Also, make sure you are using a current limiting resistor...
