I had light pink spotting yesterday [8/14/20] it didn't last very long and did not cause any other issues and didn't get heavy like my period normal does. this is abnormal for me. is it possible implantion 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.
