I am a 13 year old girl and i have a pea sized bump near my vagina what is it?

Evaluation: If the bump is growing see your doctor to be evaluated and find the cause so be treated.

"Small bump": This is probably just a mucus cyst, as the onset of major hormone production at puberty causes stimulation of mucus secreting glands "near the vagina". If painful or inflamed, see a healthcare provider, but most will rupture or break on their own.
