Clearblue - Advice

Just wondering how bad the Evaps/indents are on the early results clearblue. I took one today and I could swear I see something but my camera just wont pick it up ... that box is as paper white as they come but in person I see it. This was around 11 minutes after taking the test it's now an hour and I can still see it but its not getting any darker with drying. I'm 2 days late but this is my first cycle since a miscarriage so I have no idea if my cycle is even regular (Miscarriage was in Nov)... should I be seeing a striking blue line if I was pregnant?

This is for sure an indent????
