It is possible that you could be pregnant if you are bleeding dark brown blood about 14 days after your period. This type of bleeding, known as implantation bleeding, occurs when the fertilized egg implants in the lining of the uterus. Implantation bleeding is usually lighter than a regular period and may also be accompanied by mild cramping.
