Implantation or period ?

Ma

My period was 6 days late and has only come this morning but it’s really light (my periods are usually pretty heavy, usually bright red) but today pretty odd colours for me ranging from brown to a red/pink But I’m not sure if the odd colour is just because my period came late or if it’s possibly implantation. Can someone please help me out

Early this morning

Later throughout the day
