Period 2 days late but only brown discharge??

My period was due 2 days ago and I am very regular!

I had spotting just when I wiped 4 days ago so 2 days before I expected my period.

I’ve had no noticeable cramping, no spots like I normally get and no proper period.

I thought it was coming yesterday as there was a little browny discharge when I wiped and again this morning when I wiped it was like browny very light blood as if my period was coming but nothing all day!

I put my menstrual cup in and when I cane home to empty it it’s just clear liquid and some browny gunk around the rim!

Could this finally be my BFP?!
