So im 13 years old and I havent gotten my period yet. Yesterday I was going to go to the bathroom and found a streak of brown in my underwear where my vagina is. I didnt know if it was my period or not so I put in another pantiliner and waited till today but now I have light brown/white discharge again. Could this have been my period or is my body telling me my period is coming soon. If it is coming soon, how soon? Thanks!!!:-|
