WOMEN ONLY PLEASE!!!?!

Doesn't sound like an infection.
I think it's just a warning that your period will begin soon.
don't worry :)

hey don't worry about it i had the exact same thing and it was because i was about to start my period the heavier the brown discharge becomes the closer you will get to having your first period sometimes the brown discharge might disappeared for a few days but it will come back just make sure you wear old pants that you don't mind throwing out because the brown discharge can ruin's pants but it can be washed out, hope this helps

it could be a first period.
dark blood is usually old blood, sometimes at the end of a period it turns from bright red blood to dark brown blood.
because 1st periods are usually light and can be dark blood because the flow is slow.

I think this just a natural discharge coming along with maturity, don't worry too much unless you have some pain involved, good luck

It could be dried blood that just didn't make it's way out until now. Or an infection. Go to a doctor about it, or your mom, aunt, someone.
