Thanks for the query.
According to your description I am thinking that you are using the tablets after ruling out the pregnancy
In that case, after completing the 5 days tablets within one week you can get withdrawal bleeding.
So after stopping the pills you wait for one more week.
If you do not get periods by that time, consult gynecologist and go for ultrasound
