Drinking Too Much Water Delay Period

Ashley
Is this true? For three months I've been drinking 128 ounces (1 gallon) of water. A coworker knows I'm on the verge of four days late (I'm guessing it's not coming tonight) and said it could be because of my water intake. But would that explain my very sore boobs? I'm trying to find answers that aren't pregnancy related to being four days late.
