Hello, I'm a 17 year old girl and I was sexually active 2 weeks ago. I recently ran along 3 bumps inside my vaginal area, it burns whenever I use the restroom, and an occurring itch happens from time to time. I was wondering if I have a STD or what kind of problem am I having

It could either be an STD or possibly a yeast infection. If you have a local health department, you can start there for diagnosis and treatment.
