Indent on diff tests? 9dpo

Sarah

On 8dpo I used the strips and thought I saw a faint line/shadow of a line. I wasn’t sure if it was an indent so I kept testing. On 9dpo, I saw the same shadow line on the strips so I used the FRER and saw a faint faint line/shadow. A few of my friends who I sent the pictures too definitely see a line. One asked about indent but it’s two different tests, so I’m not sure! I’d love any input!! The strips are from 8dpo and FRER is from 9dpo
