When i finished my period yesternight which lasted 3 and half days and today when i was on instead of me releasing discharge it was plenty blood coming out and i also started the perio 2 days early why? i am confused if its implantation bleeding?

One cannot tell yet: Wait. A positive pregnancy test can tell a woman that prior spotting was actually implantation spotting. It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period.
