Pink to dark red period? Normal?

Started out as pink, and now it's sorta dark red? Was late for 3 days and usually i have heavy flow from first to second day (it's past midnight already),
​but when I check my sanitary pad, there seems to only have 2 spots of blood. When I wipe, there is a flow of blood which continues. I guess I'm out? Anyone experience this and got a bfp? I never ever had such a weird colour in my period, mostly bright red.
