Pregnancy test help

This is one of the first times taking a pregnancy test and I need help. I took the test that’s in the picture on the second day of my placebo pill with no period yet. I see a very VERY faint line. The next day I bled VERY light. I took a test the following day and I don’t see anything. I’m on birth control. I am not sure if I should take another test or if I am over thinking. Any thoughts??
