Hormones: I'm not sure what type of answer you're looking for, but breakthrough bleeding (assuming there was no trauma to the vagina or cervix as the cause of bleeding) is going to come from the uterus and is determined by hormones. Brown discharge is old blood. See a gynecologist if the answers you are receiving on healthtap aren't to your liking. An exam might be a good idea, if the bleeding unexplained.
