Weird Discharge After Fingering?

Hey y’all, i’m 17 and recently when my boyfriend fingers me after the fact when i come home and go to the bathroom my discharge is different, it used to be a crimson color with some clear but i asked on here what that could be and got a response that said he probably scratched my cervix. today he fingered me for the first time in about a week and my discharge looked a mix of gray and dehydrated period blood, i’m thinking that i’ll see how it looks after my next cycle comes and goes but does anyone have any idea what this could be/has it happened to anyone before? thank you so much, any response helps my mind calm down.
