I've been monitoring my blood pressure the last few days per my OB. I have ranged between 135/81 - 149/77. I just took it and it was 150/100.. Then I took it again 5 minutes later and it read 132/80. Is it normal for it to jump like that? About an hour ago is when I got the 149/77 so I checked it an hour later to see if there was any change and then it was 150/100.. Should I wait another hour and check again? I am just worried that is way too high! The rest of my pregnancy I have been in the 120s.
