Hi first of all you have to take this medicine for 20 days ..then when you stop you will have bleeding just like periods and then it will stop.
Secondly this is just to manage this bleeding that has been going on for 20 days
You need to get evaluated for what the problem is ..
Weight ...pcos..excess
sugar intake ..lack of exercise..junk food..
Or something else..
Then you have to manage the underlying cause so it doesn't happen again
Also please do not wait for the bleeding to stop for 20 days...get your Hemoglobin evaluated by CBC test ..get help if bleeding doesn't stop timely
