Well pee doesn't smell like roses lol. Jk. I had a similar experience as well. While you were drinking you probably pissed a lot and it was clear mostly? Well now that you aren't drinking as much fluid your urine is darker I would imagine? It may just be now you are remembering what urine actually smells like? But since your gf noticed maybe there's something to it. Give it a few months and pound water. Shee what happens.
