Implantation or period?

Katie

Hey, I’m so confused I’m not sure if it was my period or implantation bleeding, it was more than spotting but far less than a period it lasted 2 and a half days and it was light pink/brown I had no clotting either and mild cramps I haven’t been able to get a pregnancy test yet I’m just so confused if it was my period just being off or if it was implantation bleeding
