Very faint postives and some negatives ... So confused

So I am 3 to 4 days from starting my period (11dpo) I took a 1st response pregnancy test 2 days ago in the evening, just out of curiosity, and I got a very very faint positive. Last night I took another 1st response and a clear blue negative, this morning took 1st response and clear blue, 1st response looked like maybe a faint faint positive but not clear, clear blue negative. Only thing is I drank a lot of water yesterday and peed like 6 times before testing, last night I drank a glass of water before bed and woke up to pee around 2:00am and tested at 6:00am. Am I crazy or is this a very faint positive?🤦🤷 Has this happened to anyone else, faint positive then negative. Should I wait or maybe false positive? Maybe too early or I drank too much water.

This one is from this evening, almost exact same as a couple days ago.
