Preeclampsia?

I have all the symptoms but high blood pressure. It's been 120/60 when before pregnant it was 90/60 usually. I'm just wondering if you guys have a urine test every appointment? My doctor only gave me one at my 10 week appt. I feel like she should check for proteins in my urine.  All she ever says is its all normal. I'm gettin so frustrated! I'm 36 weeks btw.
