Ketones in urine


I'm 32+ weeks and at my last appointment on Wednesday they said I had a trace of protein and some ketones in my urine. I work in a lab so I took some urinalysis sticks home and just tested again I still have trace of protein but I have moderate/large amounts of ketones. Does anyone have experience with this?

I drink loads of water and GD test done at 26 weeks came back normal.
