Thank you for your question. I'm sorry you are having such unpredictable bleeding. It is very unusual to bleed like this from the vagina or cervix. If so there may be something that is causing the bleeding like and infection or injury. My suggestion would be to see a gynaecologist who can examine you and determine the source of the bleeding and treat it correctly. You may need an ultrasound examination too if local examination does not reveal the cause. best wishes
