"white coat syndrome"

So I've been "diagnosed" with "white coat syndrome" which basically means every time I see my doctor my blood pressure is super high . Usually she just gets me to wait and lay down and then she checks again and it's fine . But last visit it remained super high and she sent me to the hospital . I've had an uncomplicated pregnancy so that freaked me out . This was at 34 weeks.  Once I got to the hospital they monitored and tested and told me I'm fine . The doctor did of course warn me of risks of high blood pressure etc. But I was wondering if any one else had this happen to them ? Or if I should be concerned ?  Thx xo
