Has anyone experienced high protein on a urinalysis while pregnant?

Ra

I recently went in for my routine labs at 9 weeks pregnant. They results for my urinalysis came back and I had 100 mg/gl. Normal is between 0-27mg/gl. I was told by an RN friend that it could be caused by a kidney infection or even high blood pressure. I am going in for a liver and kidney function test tomorrow. Has anyone gone through this? Is this something I should worry about?
