Faint positive tests

Heyy I’ve just this morning taken 3 pregnancy tests all different brands and they all have a faint line. I then decided to use the CLEARBLUE early detection digital but it said not pregnant. Im unsure what to think as it says they are a sensitivity of 10. Here is one of the faint lines on the Wondfo test just to show you. Has anyone ever had this happen with tests before? Thanks ☺️
