Bleeding from vagina and not on period

Patient: Im 16 years old . 3 days ago I started getting a brown discharge and then some blood now theres barely brown and its mostly blood . I already have had my period for december so i dont think it could be that unless it comes twice a month ? I should be getting my next period in about a week . The blood is a light red and it doesnt hurt or anything down there .. Im really scared cause I have no idea what it is . I am still a virgin and never had any sexual interactions besides kissing .. Please help . Is this normal ?
