Faint lines - is there a chance?

Allegra β€’ πŸ‘©πŸΌπŸŒˆ I love autumn and my dog

So today I got very very faint lines on two different pregnancy tests. How likely will I get a bfp in few days? I’m 10dpo. I read it can happen just before AF. Does anyone have a personal experience with this? Thanks for your opinions.
