Sugar I would test with some more IC's, I think I see a line on the one you posted but it wasn't dry so hard to tell at that point. What are those other tests? I'm currently 5 weeks pregnant, had brown and pink spotting upon wiping for 5 days from the day of bfp so if your AF isn't usually light you could definitely still be in with a chance, I thought I was maybe having a chemical but my lines have got steadily darker xx
