Implantation bleeding?

C

This is the second time in one day that I've noticed this. The first time there was more but it was the same colour. I'm 8dpo, I'm due for my period on the 25th July

I've been getting cramps, headaches, sore boobs, some foods make me feel sick, I've never had this happen before and I never have cramps whilst not on my period, my periods are very regular and I've never had any type of blood before my next period
