Anyone else? Pre-eclampsia??

Victoria • First time mom, due date is 10.16.16 but baby girl is breech so we are having a scheduled c-section 10.10.16🎀 MKW💜
31 weeks and Doctor found 2+ protein in urine and sent it off for culture.. I only have one kidney that functions. I haven't had any protein in my urine or uti's my whole pregnancy this is the first time and I've read most of the time it means pre-eclampsia..?? My blood pressure has been around 120/78 every time I've went to the doctor... 
Has the doctor found protein in your urine?
Was it pre-eclampsia?
What did they do if it was/wasn't pre-eclampsia?
