Hi,
If this isn't your monthly period, then you need to see a doctor right away. Bleeding for a long period of time after rough foreplay (fingering) or after sex, isn't considered normal. You should make an appointment for a pelvic exam with you doctor as soon as possible, or visit a health clinic for a pelvic exam, to figure out what the cause of the bleeding/watery discharge is and how to treat it.
