I agree with the others. First periods are often just brown discharge.
When you say "lately", Bloomerxo - do you mean in the last few days, or do you mean on and off for weeks? If it's in the last few days, chances are that's your first period. If so, your next ones will probably be more normal with heavier red flow.
Best wishes. Can you talk to your mother about this, or do you have older sisters?
It does sound like the early starts of your periods coming on. Brown discharge is menstrual fluid that has stayed in the uterus for a little while before coming out. A lot of women who have regular periods have brown on their first day and then red after that, but a lot of girls just beginning their periods have couple of months of just some light discharge that is brown, only. You're on track.
Hi Bloomer, your ok but it sounds like its on its way, dont frizz, it will happen when it happens.
Good Luck
