It’s hard to tell with blue dye tests as they basically always look like this, whether negative or a faint line. I’d test again in a couple of days or with another test. Good luck.

If it's the equate walmart brand that is like 3 bucks please don't trust it. I got my hopes up last month because I had a dark blue line on all 3. Pink due tests all said negative. My period showed up right on time.
