I have a bump on my labia minora, which was redish, purplish. i popped it thinking it was a pimple. it bled a lot. could it be herpes?

Unlikely. : Herpes isn't a bump but a tender sore. You can't pop herpes.

Not Likely!: What you are describing is not characteristic of genital heres. Genital herpes, a sexually transmitted disease, is caused by the herpes simplex virus type 2 usually but can be transmitted when an infected mouth infects the genitalia of another. It causes a painful rash that may form blisters which causes a yellow fluid filled bumps that when bursts can form ulcers that crust over seldom bleed.
