Brown vaginal discharge can be related to your period, it's known as spotting and caused when blood mixes with discharge and takes time to leave the body (thus going brown). It can occur just before or after your period, light periods may be only light spotting like this, or brown discharge can be an indication of bleeding for other reasons like hormonal imbalance or ovulation spotting.
