i am 13 years old and I haven’t had my period yet. I woke up one morning a couple weeks ago with brown stuff in my underwear, it wasn’t gooey it just looked wet, a little like diorreah. Ever since then, I haven’t gotten it again. I have only been getting normal clear discharge. Does anyone know what the brown stuff was and what it means?? Does it mean my first period is near and why did I only get it once?
