Brown Discharge What does this mean😭

Okay I need some honest answers here and I'm freaked out.
I'm 16, on birth control since November and sexually active but use protection (condom)
I've recently started getting brown discharge and it's starting to freak me out.
I know it stupid to google diagnosis yourself but I wanted an idea of what it can be. 
Like idk maybe this has happened to someone else maybe someone knows what it means.
Even if you aren't 100% sure just give me an idea.
I'm planning to go see me doctor but you know I'm young and I don't feel that ready for a vaginal exam expecially if it's just like some egg shedding or something to do with my birth control.
Period was 2 weeks ago next is in another 2 weeks
