8DPO and 9DPO faint lines question.

Katie

I know I’m early but using 6 days sooner test. 8DPO I got a faint line I thought for sure it was and indent due to people replying it was. Well my 9DPO had the line again but clearly more visible. Should I assume it’s an indent as well or it darker it is possible an early faint positive. When the best time to test again? Tomorrow or 2 day wait.
