Opinions? Not sure...

Hi! I got a "positive" on accumed yesterday... I think it was 7 dpo (I have irregular cycles) tested again & got a faint positive. I figured it was because my hold wasn't long enough due to me feeling anxious. I got another faint today on accumed, so I bought a clearblue & nothing... at this point I'm thinking the pack of accumed I bought off Amazon is just faulty. But I'm also thinking how can the whole pack be faulty?! Opinions please. Pictures below...

#1 is the positive I got yesterday, #4 was also yesterday. #2 & 3 I dipped in water to see if pack was faulty. 5 & 6 were on an hour hold so they don't really count lol. The clearblue was today & I didn't want to spend $25 on first response but at this point I should have because I'm still left wondering
