Possible late bfp??

I'm on CD38 and no af so far. I have extreme breast tenderness and soreness from last 10 days. On Apr 6th I got a bfn, after that I was expecting my period would show up. But, no sign of it yet and I was never this late, although I have pcos and my cycles range from CD 31-34. I had a brown spotting on my undies on Apr 5th,

I had implantation bleed in previous pregnancy on 6 dpo and got a bfp on 11 dpo

But, I'm terrified to test now, as I am tired of seeing another bfn 😑

Update : I got my period today on CD 39
