Salt and urine plus a test strip

Anyone ever tried the salt and urine test? Apparently if it doesn’t do anything your not pregnant, but if the urine turne milky or cheesy it’s positive ? Okay so I done this and then dipped a prey test strip in there and got this result? Even tho I’ve had 3 negatives before hand, I know these tests aren’t reliable lol but it was dojng it for fun to see if it actually works but idk someone help?xx
