I have brown discharge and its not time for my period yet and I'm not on any birth control and trying to get pregnaunt what does this mean ?

Could be a good time for a checkup with your ob/gyn doctor.

Sometimes women have breakthrough bleeding midcycle... this is nothing to worry about. If you are close to starting you period, you could just be spotting before your regular flow starts.

Brown discharge is just old blood... it usually is nothing to worry about.
