How likely is 2 indents?

Taylor

I took a premom and I swear I saw a faint line (it was about 3.5 minutes my timer went off and I had to walk to the bathroom). So, I took a FRER and I saw another faint line, but not until about 5 minutes. I will post the premom one, but the FRER is hard to see.

I’m not sure if they’re indent or evaps because they weren’t after 10 minutes?
