Is this normal?

So what I believe was implantation spotting was 8 days ago. Since the 26 and 27 and today I’ve been getting really faint lines. Can’t really see on camera though since it’s really not picking it up. Is it normal to stay so faint or is it supposed to be getting darker by now? Trying not to get my hopes up but at the same time I see faints in person on two different test. Never had a problem with indents on the easy@home ones I been using for 3 years now.

-Thank y’all for y’all comments but again in person they are faint but not picking up on camera. I guess I’ll just keep testing to see.
