Wonky test results?

Hey guys! I AM waiting to hear back from my doctor but I figured I’d ask to see if anyones had this happen. my diabetes test came back forever ago normal and fine and my dr takes urine tests at every appt and they have been completely normal up to this point. today however at my 33 week appointment I had protein (30mg) and ketones (80mg) in my urine. I’m not sure what this entails and my BP was great today so I don’t think it’s preeclampsia? I’m not sure though. does anyone know what it means?
