Hi, thank you for asking Healthcare magic
I have gone through your query and understood your concerns
Given that an ultrasound
showed nothing, then the probable cause of bleeding is dysfunctional (abnormal) uterine bleeding
. This results from hormonal
imbalance within the period. It can be managed with oral contraceptives. If I were your treating doctor, I would put you on oral contraceptives.
I hope that answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. We will be delighted to answer more questions from you.
I wish him good health
