Thanks for asking your query.
As you had mentioned that at doctor's office it is 200/120 twice.This is not a normal.
Blood pressure recorded at one time doesnot mean that you have hypertension
I would advised you to record your blood pressure atleast three times daily preferably at same time of the day.
Avoid tea, coffee, heavy exertion 30-45 minutes,be relaxed prior to Blood pressure measurement.
If still your blood pressure is on higher side than you need to follow lifestyle modification as ( relaxation methods,exercise, avoid fried food, less salt, include more fruits & salad in your diet). If this lifestyle modication does not improve your blood pressure in a period of 3 months than you need to be started on antihypertensive medicine.
Wish you a Good Health.
