Is it possible to dilute pee?

jassy

I had a positive last night. Negative this morning and at the doctor.

I just had to pee when I took the test last night but I drank so much stuff this morning to do the tests. My pee was near clear.

False positive is rare so I’m really trying to understand what’s happening.

Can you dilute with a lot of fluids. Like if you’re very early on and not enough HCG?
