Should I be worried they’re not getting super darker?

* scroll to the bottom to see all of them they all have lines just zoom in** Period is due today and hasn’t arrived I’ve been testing a couple of days and I’m worried that they’re not super dark by now. I don’t know how long I should wait before I freak out. Help is appreciated 😅 they also result lighter during the day. I know they’re not indents because they have pink color to them. They’re all separate tests
