Implantation bleeding?

Kurstien

Im not sure if im on my period or if it’s implantation bleeding but when I wiped 3 times today it was all very light pink. I did take a test and it was negative. Could it be implantation bleeding?

I’m normally med/heavy flow but it’s weird this time. I’m supposed to start my period today but it’s been really light. I’m cramping and have breast tenderness
