Implantation? Ovulation? Early Period?

I think I’m about 6DPO, but I’m not 100% sure I did or not because I’m not very good at reading OPKs. I had a bit of spotting this morning, could it be implantation bleeding or did I get it wrong and I could be ovulating now? Or am I starting my period early? It would be over a week early...
