Implantation ?

Black Qùëëñ

So I ovulated around January 1st, I bd December 25,26,27,28,29 and January 1st and 2nd

I started spotting on January 6th but the blood was brown and I am still spotting today, could this be implantation bleeding??? because my next period is not due until January 16th, my boobs are tender and I have light cramps
