Implantation dip or spotting?

Sarah

I’m probably grasping at straws. Wondering if this is an implantation dip or my period. I’ve had a bit of spotting this morning and have had nothing since. Colour was light pink. My period usually starts off heavy either bright red or brown. My period is usually on day 27 and it’s CD 25, 11DPO.

Please be kind, feeling a bit hopeless.
