Protein in urine

K67

The last 2 samples of urine I gave at my appointments had bits floating around in it and I wasn't sure what it was, turns out I had protein in my urine. I know this is a sign of preeclampsia but it was never mentioned by the midwife she said come back next week (tomorrow) for another checkup. Does anyone know what this could be I don't think I have a uti or kidney infection as I feel fine and no pain passing urine
