Weird discoloration on T line?

I'm not trying to grasp at straws. I'm still waaaay early, especially to be taking a dollar store test and not a frer but, this test has a weird shaded area over the test line. Is this one faulty or could something be starting? I only took it because I've been waking up at 5 am the last two days and vomiting for hours. Exhausted but I can't sleep. 😩
