Hello Good Morning Recently I Noticed That My Urine Forms

Hello good morning recently i noticed that my urine forms like a bubbly foam in the toiled so i went Did a urine analysis it came back all normal but i have one question i did drink like half a liter before the test by 1 hour so i can be able to take test and at that time during test i did not find any foamy bubbly liquid is it because i made the test go false because of the amount of water i drank ? Should i consider taking test again ? But this time not drinking water ?
