Dark brown vaginal discharge and blood
I'm 20 years old, female, and NOT sexually active. For about the past week I've had this dark brown discharge to the point where I have to change pantyliners two or more times a day. My last period was three weeks ago, and it's usually a week to nine days late, never early. Yesterday and today, along with the brown discharge, I've been eliminating red blood, but only when I use the bathroom - it doesn't show up on the pantyliner. I've been under a tremendous deal of stress recently. Is this something I need to worry about, or is it due to stress and/or ovulation?
