Pee is alwaya dark?

Paige

Hey, so im a little worried, i drink ungodley amounts or water a day, over a gallon, but my urine is always dark like im dehydrated, I eat alot of tums at night and im scared this might be bad for me, i normally can go mostly all day avoiding them though. Is anyone else noticed this or know anything about it being dangerous? my blood work and glucose test were good, and im still taking a prenatal every day
