White Coat Hypertension

Does anyone else have white coat syndrome where your blood pressure is always high at the doctor? I've had it taken before at home and it is normal. Now that I recently found out I'm pregnant I've become really anxious about going in and worrying my blood pressure will be super high. I know that is not a good thing to have while pregnant and it makes me more nervous that I'll cause something to go wrong with the pregnancy. I'm going to buy a BP monitor to take it at home and I'll be able to show them in case it is high. Anyone else gone through this?
