Has anyone had multiple days of weird discharge instead of period ?

M

Hey girls,

I posted a few days ago on sunday the sixth with this weird discharge. Monday it got a little darker in color-taupe color. Tuesday it felt dry then tues night it became dark brown almost black. Thought id def get my period but now on Wednesday i only have a streak and it looks like a poopish brown color. The past few months my period has been weird where i get discharge maybe a day or two then my full blown period but this time this is going to be my fourth day, has anyone experienced this? Took an hcg cheap strip test and it was negative yesterday

Sunday
