What dpo are you? Last cycle I had some pretty convincing looking shadows which appeared to have the faintest pink hue to them, then after nothing. Until 14dpo, so five days after those shadowy looking lines, I had clear positives. Sometimes these tests will show up things which look like early positives which aren't, only to then later on see an actual positive. They're a little hit and miss these ICs! Hoping for a good outcome for you
