Has anyone used a clear blue test a week or more prior to period?

They're intended for use four days prior, and the early one can be used 5 days prior. I just wondered if anyone had ever used one a week or more early and received a positive?

I think it's more based on your ovulation dates rather than your period dates. Anything before 10dpo and it's highly likely to be negative even if you are pregnant, this is due to implantation. Do you have any idea on when you may have ovulated? I got a positive at around 10dpo on a clear blue early detection
