You need to be examined by the Gynaecologist for these symptoms. It is menorrhagia or prolonged menstrual bleeding and the causes are many like hormonal imbalance, fibroid uterus etc. For the bleeding to subside initially Homeopathic Medicine has remedies like Belladonna, Trilllium Thlapsi etc. and once the cause is diagnosed further episodes or menorrhagia can be curtailed by treating them with these medicines.
I am sure Homeopathic Medicines will be of help to you.
