Help me!

Ok I collected urine to use for a test first thing in the morning. I didn’t end up being able to run to the store today so I went to go dump it after 11 hours and it looks like this 😟 what is this white stuff..?!!! It wasn’t there when I originally peed 😭 I wiped before I peed into the jar

Af is 7 days late does this mean I have an infection I have NO pain I’ve had a uti/kidney/yeast infection once before so I know what it feels like and I don’t have any symptoms of that.. help what’s going on..???
