Hi thanks for your question
You were put on tab Duphaston
10 mg daily for 12 days by your doctor and you have completed 12 days course.
You had bleeding after stopping Dupaton,and you think this is withdrawal bleeding.
Yes, this is withdrawl bleeding and this is also your period for this month.
Since 12 days have already passed, you wait for anther 16days; hope fully you will get regular bleeding from next month.
Hope I answered your question.
