Protein in urine

Ra
My urine test this week showed trace amounts of protein. My doctor didn't bring it up, but I saw in my notes. I've been having headaches and seeing spots, but my bold pressure is 117/72. She said she wasn't worried since my bp is good and just to keep an eye on things. I know it can be a fluke or sign of other things. Did anyone have it at/after 30 weeks and it turned out to be nothing?
