What is the reason for spotting one week after taking oral contraceptives?

Patient's question:

No

Doctor's answer:

Hello, it is possible to experience vaginal bleeding about a week after taking birth control pills. This is a hormonal withdrawal bleeding, which is a normal phenomenon. Generally, the bleeding duration does not exceed 7 days, and the amount of bleeding does not exceed the amount of a menstrual period. There is no need to worry.
