If you bleed a week after your period, you may have physiological bleeding, which is ovulatory bleeding. Ovulatory bleeding usually occurs about 14 days before menstruation, that is, about the sixteenth day from the first day of menstruation. Since ovulation is followed by two peak periods of estrogen, this time may stimulate the endometrium and delay a small amount of bleeding. The bleeding does not last for a particularly long time and will be over within 3-7 days, which usually does not affect health and occurs once in a while.
