What happens if you wet a pregnancy test with water?
Presumably, water will give a negative result (we hope!), but you still can’t then add your urine to the strip as well. If you reuse a strip that has gotten wet — either with water or urine and even if it’s dried — you may get a false positive. That’s because as an HPT dries, an evaporation line can appear.

After peeing in a cup, add a few tablespoons of water to your urine so it becomes lighter in color. This might work because it reduces how much hCG you have in your urine. You’ll still have enough of this hormone for the pregnancy test to “read,” but not so much that it’s overwhelmed.

Even if you did miss your period but it hasn’t been at least a couple of weeks since you conceived, you could still get a “false negative.” That’s because you need a certain level of a hormone called HCG (human chorionic gonadotropin) in your urine for the test to work.

Diluted urine occurs when there’s too much water in the urine. It means the urine’s concentration is weak. As a result, the tester will be unable to properly detect the presence of drugs in the urine.
Can drinking too much water affect pregnancy?
Morning sickness, acid reflux and tiny bladders usually prevent you from chugging too much water throughout the day. Women who drink a large amount of water (1 to 2 gallons) in a short period of time could be at risk for water intoxication. When this happens, your body takes in water faster than it can filter it out.
