Implantation bleeding

baby3love

Is it possible to have implantation bleeding at 12 DPO? I’m two days away from getting my period but today at 12 DPO, I had smears of brown discharge like old blood. I was disappointed cuz it was a really nice sexy panty and also sad I was gonna get my period but then now nothing...no cramps or swollen vaginal feeling!!! I took a pregnancy test on 11 DPO and got a BFN! Has anyone had late implantation before near their period?
