CM CHECK with blood

Jessica • Baby Casey 9.12.17 💙💙👼 miscarriage 5.6.18 & 6.7.18 Baby Eloise 19.9.19 ❤

So I went to check my cm and it was eggwhite. But when I wiped about 30minutes afterward there was pink blood. did I scratch my cervix or could this be implantation bleeding? has anyone done this before?
