Blood pressure worries

My blood pressure usually hangs steadily around (very very steadily) 120/70. In my second trimester it's running 140/80. This is pretty off from my usual and even pregnant with my twins stayed firmly in my normal range. They found trace amounts of protein in my urine but not enough to trigger a positive protein count. Should I be worrying? Am I worrying for nothing? They aren't taking me seriously. I see the midwives on the 15th. Will the listen better? I want to stay with the midwives. If I have to go back to the big hospital I have no choice but a repeat c-section...
