What is ovulation bleeding?
Ovulation bleeding is light bleeding, or spotting, during ovulation. Ovulation is when a mature egg is released from the ovary. If you want to predict when you're likely to be ovulating, try this ovulation calculator.
Some people experience spotting during every cycle, others only a few times, and some never do. Ovulation bleeding is characterized by very light bleeding, much lighter than a period, and typically lasts one or two days.
The color of vaginal discharge from ovulation bleeding may range from light pink to bright red or dark brown, depending on the speed of the blood flow. Light pink spotting generally means that blood has mixed with cervical fluid. Ovulation bleeding is generally caused by changes in hormone levels, specifically, a dramatic fall in estrogen that happens right before ovulation and may cause the endometrium — the inner lining of the uterus — to shed.
