yeah like the previous said, before your period is due, and nothing like a period. But, if you still have any doubts, go get a test and take a test..or your period could also be different because of stress or many other things...
Implantation bleeding is usually about a week BEFORE your period is due and its just spotting when you wipe.
I dont think implantation bleeding lasts that long,it usually when you wipe you notice it,its not like a period.i believe its very little.possible your body is going through some changes.
