I copied and pasted this description for you, hope it helps...


Description some women will experience spotting around the time of ovulation or shortly afterward. This is likely due to fluctuating levels of the ovarian hormones estrogen and progesterone. This is a variation of the normal menstrual cycle and should not cause you concern unless it increases in quantity.

Mid-cycle spotting

symptoms ovulation bleeding happens without other symptoms of a menstrual flow. The bleeding is pink to red; light; 1 or 2 days in duration.

Bleeding episodes at 2 week intervals suggest lack of ovulation. This can also occur with irritation to the cervix, polyps in the cervix or the uterus. These issues are addressed by clinical examination, perhaps combined with ultrasound image of the pelvic organs.
Other symptom may include abdominal pain.
