implantation bleeding

carranza

okay so i am 10 days late and like 2 days ago i start spotting pink/brownish blood/discharge but only when i wiped. it was barely visible those days but today it was only brown blood and more than the first 2 days but not enought for it to be considered my period. the blood is only there when i wipe. also yesterday i took a pregnancy test and it was negative. could it be implantation bleeding? and could i be pregnant ?
