I was put on meds when my blood pressure hit 140/90 @32 weeks. I had blood tests done but they were fine even though I put on 6 kilos in 2 days!all bloat!.
My blood pressue continued to climb and at its highest was 170/110!
It wasnt until I was admitted to maternity for the first phase of my induction due to macrosomic growth that protein was found in my urine. Quite high levels apparently...on the upside- I was down 20kg 2 days after the birth of my son.

Good luck!
