Hello madam, your history is incomplete? You haven't mention about your age and marital status, weather you are sexually active.....well from the history you have given, profuse bleeding following 3 months of amenorrhoea, first thing is to rule out pregnancy
....it can also be due to underlying disorders like thyroid
, sometimes also because of presence of any polyp or a myoma
. ...i would suggest you to consult your gynaecologist. ..you may require an examination, only then the under cause can be detected. ....hope i was helpful to you. ...
