weird colored urine

Sarah
So when I tested just now ( was negative) my urine sample was so dark it looked orange. Today I have drank almost a gallon of water already, so I don't think it's dehydration. I haven't changed vitamins or anything and I ate pretty mild stuff today (grapes, stroganoff, banana) and there's no burning or blood or urgency to go like a uti. I have never had this before, is this maybe a thing with pregnancy? Thank you for your input!
