Diluted Urine

Jasmine

Hi! Now I’m stressing. I got my positive three days ago. I was curious to see if my test lines got darker so I tested today and my urine was almost clear because I drink a lot of water…. The positive line was SO faint. Especially to the very dark line I had three days ago. Is something wrong? Is HCG lowering which isn’t good…. Or does diluted urine do this?
