I found a light yellow circled pill. It only has markings on one side. The side that does have the makings it has a cross on it but it fits only 4 numbers and on the top left it has a "0" on the top right has a "2" on the bottom left has a "2" and the bottom right has a "1" I have no idea what this pill is I've tried looking it up but maybe I'm not doing it right, I'm not sure. Thanks for any help i can get.
