I’ve taken 4 tests so far, 2 clear negatives and 2 possible faint lines?

I took this test this morning and photos were taken within the time limit. Yes, I’m aware blue dyes can be very misleading but I can see slight blue in the line and I also got a slight pink line on the last test before this one. I’ve gotten indents before but never with color? Photos shown are edited and non edited.

I have an appointment tomorrow so I will find out more then hopefully🤞
