implantation bleeding

im not sure if im getting my period or if its implantation bleeding. this just happened today and if it is my period it is 3 days early. which is not normal considering the fact that ive been tracking my period since last august and it has been spot on to the day ever since.

The bleeding was really light and didnt feel like a normal period. I dobt remember having this shot on during my first pregnancy. we have been trying for over a year to get pregnant,so lets just hope this is it!
