The BP is probably more of a worry when in combination with the protein - My bp went up to over 135/90 in my final week with DD when it had been around 100/75 - the doc sent me to hospital for bedrest and monitoring and when it didn't go down but up over 3 days they ended up putting me on meds and inducing me early - but it was more to do with the BP than the protein. I also had a fair amount of swelling in my feet, ankles and legs and was fairly overweight at 100kg. Do you have much fluid retention or swelling? I believe that can be another sign of PE.

Hope everything goes well for you and that you don't have to worry about possible induction.
