Last two weeks, it's hurt when i push my poop out. i've used both prep h and vaseline, but still hurts when poop. any advice? thank you!

Fissure: Most likely you have an fissure. It's when u have small tear in the lining of the anus. Starts with an especially hard stool that u strain to evacuate with resultant tear.Keep the stools soft by increasing the fiber in the diet. Keep yourself well hydrated. Avoid straining or the fissure will get worse. While you doing that get expert medical advice from your primary care or gastroenterologist.
