Don’t know what to do..

i’ve been having TONS of pregnancy symptoms, period is 3 days late, ive gotten a few faint positives but they fade so quickly and they are so so so faint. the other tests are just plain negative from what i can tell. i’m not sure what to do. i’m concerned that the faint positives i’ve had are just some type of tweak in the tests. they haven’t been getting darker or fainter it’s literally one day i’ll get one or two and then another i’ll get none even if i haven’t been drinking a lot of water to dilute it. someone help please
