Pregnancy test

Love

So yesterday would of been 11 dpo 3 days before period. i took 7 test 5 came out positive two lighter then these but i also took them 30 mins later after downing lots of water took another 2 came out negative so im very confused on how that is. Is it because i had to much to drink? I know for sure you cant get 5 positive inless somethings wrong all of these showed up in 2 two 3 min mark. Had my cousin watch one test with me cause i couldn't believe it. Do these look positive right??
