1+ protein

What does that exactly mean? My doctor said that it could mean mild preeclampsia but didn’t technically diagnose me with it.. he’s having me do a 24hr urine check and then I’m going back in a week to look at my blood pressure and check on my baby my blood pressure was 134/95 I am currently 35+5 and have a scheduled c-section for 39 weeks.. does this mean that I do have mild preeclampsia or I could have it?
