I thought this was supposed to be "clear"?

So on Tuesday of this week I knew I had to go to the dentist for some pain and because I'm me, knew it'd probably end up with some strong meds. So I decided to take a test that I wouldn't worry about med type.

I peed on the stick and after a minute there wasn't anything so I tossed it in my drawers and went on.

Two emergency root canals and... My bed is my best friend.

Today, I happened across the test again but it now has a literal half positive line. Like, only the bottom half. So what am I looking at? This isn't clear blue at all. Am I or am I not?
