Should I still be getting darker at this point?

Anyone testing around this time? I feel like others I’ve seen the second line is getting lighter and I can’t help but think my test today (18DPO) my second line is wider and maybe my first line not even as dark. 😔

I have a Dr appointment today and I know it’s the only way I can get actual answers but meantime is there anyone that has had lines like this?
