Husky peeing so much

Why in the world is my 8 year old Husky peeing Husky every 2 hours in my house! I took her urine sample to the vet and everything came back negative and fine! She is not spayed and that my next option. This is not normal at all for her to be doing. Any suggestions. Like she will go outside and come pee inside after peeing outside and drinks so much water and can’t seem to get enough water
