Am i pregnant???

so the strips were all stark white negatives when I checked them at the 3 minute mark, but then after 1 hour they showed faint positives. the ones that showed negatives were when I was 7 and dpo. but at 11 and 12 dpo they showed the faint postives only after 1 hour. so then I took these clear blue tests and the top one and digital one was 11dpo in the afternoon and showed positive then the bottom was this morning and shows positive but it's really faint so am I actually pregnant? why would my easy at homes be stark white negatives but the clear blue show positives right at the 3 minute mark? they are so faint for 11 and 12dpo, unless maybe I only implanted at 10dpo?
