The original bloody vaginal discharge called “lochia” will gradually decrease and change to pink, then brown and finally to yellow. You may bleed for as long as six weeks. This should not deter you from keeping your six-week appointment. You may occasionally bleed heavier for short periods of time. The first menstrual period may occur before your check-up, especially if you are not breastfeeding. You should call if you are having bright red vaginal discharge bleeding that causes you to change your pad more than once per hour.
