Advice please

Hi guys, so i am so confused and kind of upset. The first two tests I took yesterday around 5:30pm. The bottom two I took this morning at around 6am. Why is the first response digital negative ? I see lines on both the lines test ( I think) but what’s going on with the bottom digital. Also I feel like the lines should be way darker by now I’m 12dpo. Am I pregnant or not pregnant?
