Bleeding this heavy for more than a week, starting with clots and still ongoing, needs a doctor's review rather than a home remedy, since prolonged heavy bleeding can affect your haemoglobin. Hormonal tablets are commonly used to stop this kind of bleeding, but the right choice depends on your history and an exam.
Next Steps
Please see a gynaecologist in the next day or two for an exam, a pelvic ultrasound, and a blood count to check you haven't become anaemic.
Health Tips
Go in sooner if you feel dizzy, very weak, or are soaking through a pad every hour.
