What causes brown discharge mid-cycle?

Ovulation and implantation bleeding are the most common causes of brown discharge mid-cycle, but there are other reasons why your discharge is brown.
It can be distressing to notice brown vaginal discharge before it’s time for your period. Brown discharge occurs when a small amount of old blood mixes with your normal vaginal discharge. Research published in the American Journal of Epidemiology found that, on average, only 5% of women experience light bleeding, or spotting, in the middle of their cycle. Still, many women may experience occasional mid-cycle bleeding.
