I'm telling you I literally just went through this but one day behind. 9 dpo first faint line, 10 looked lighter and i was convinced i was headed for chemical, 11 fmu looked just like this if not a little lighter, then a strong line finally at 12dpo. I have pics on here (testing thread starting at 6dpo) if you want to look at my pics. But anyway your progression looks fantastic! Congratulations!
