Withdrawal bleeding caused after taking oral contraceptives can appear as a spotty brown discharge or as bright red blood, coming in an amount similar to the amount on the 4th or 5th day of the arrival of the period, but the bleeding will end within 3-7 days. If the bleeding does not exceed 7 days, it is fine as long as you take care of your personal hygiene. However, some women take oral contraceptives, which can cause constant bleeding. When the bleeding exceeds 7 days, it is necessary to review the ultrasound to determine if there is any effect on the lining. Depending on the situation, oral anti-inflammatory medication and hemostatic medication can be used to stop the bleeding and avoid the possibility of irregular menstruation. It is important to observe the delay in menstruation due to the withdrawal bleeding. When there is a prolonged delay in menstruation, it is also necessary to buy a pregnancy test to rule out the possibility of conception.
