Help please

This morning I'm 9 dpo. I bought a bunch of those cheap wonderfo hpt. So I started testing yesterday at 8 dpo and 2 negatives ( morning and afternoon). I knew it'd be bfn but I'm just curious and not getting upset bc I know it's early. I also used digital opk and got my only smokey face Sunday 10/19. We bd 4x during my fertile window. Well-- this morning I took another opk just bc and I got a smiley face!!! Along with another bfn. Is that any indication I may get a bfp soon or just a fluke?!!! What's been your experience? Thanks!!
