Is it normal to be spotting 4 days after your period??... what can be the cause of that happening??

Irregular menstrual periods are common. The fluctuations of estrogen and progesterone can be easily affected by stress, weight gain/loss, exercise, lack of sleep, etc. If the symptoms persist, talk to your Dr about your irregular periods and what testing can be done to determine the cause.

See a gynecologist if you have frequent, erratic spotting.
