Withdrawal bleeding can be brown or bright red, depending on the amount of bleeding. If the amount of withdrawal bleeding is relatively small, oxidation in the vagina will result in a brown color. If the amount of withdrawal bleeding is relatively more, it may be bright red. Regardless of whether it is brown or bright red, it is normal and will not exceed the amount of menstruation. 3-5 days of withdrawal bleeding will disappear, and menstruation may be affected by the appearance of withdrawal bleeding. Most people still follow their original menstrual cycle, but a small number of people have a change in their menstrual cycle and start a new cycle from withdrawal bleeding.
