My Blood Pressure Has Always Been Normal I'm Generally A

My blood pressure has always been normal I'm generally a fit and healthy 45 year old woman but do suffer stress and hate the thought of stress which causes me anxiety in the past few days my blood pressure has shot up between 185/86 and 146/74 I have visited the doctor in last few days who have asked me to return in 3 weeks but im concerned about my bp should I re visit doctor sooner than 3 weeks suggested?
