7/8 dpo

Tara • Mommy of 2💍 8/24/09💙 04/20/12💜

so my breast was super tender during my OV week. right after my fertile week was over the tenderness went away. now today I was at work and tmi but i felt like a bowel movement was coming on so i went and use the bathroom and when i wiped there was some pink. by the end of today it was a little brown on my patio line. now my breast are back tender. could this be the start and could I be going through implantation?
