Hi I am 15, and I have been getting my period for about 2 years or so. I'm a virgin, haven't been taking any sort of medications. My periods all seem to be regular now, but what is really strange is that a couple of days ago I noticed some brown discharge on my underware, I thought that it was my period starting early. Now its te second day, Im still having those discharges and I know it isn't my period.

I am going to see a doctor in 9 days, but i'm worried should I try to go sooner to the doctor, and is this something really serious?
