Late period but bfn

L

Hey so my period was due on Saturday still nothing today. However I have been spotting either really light pink/light brown. I first spotted at the end of last week and again yesterday and a bit today. It’s not loads in fact I only notice when I wiped. Took a test today and it was a bfn!! Help am I still in with a chance? Anyone else going through or gone through this and eventually get a bfp?? Thanks lots of baby dust to you all :) xx
