With Phoebe I was sent in with BP of 140/92, but after a couple of hours in hospital with a healthy CTG, my BP went RIGHT down... I think I had a bit of white coat syndrome. So that's their first step - make sure that they test you when you are rested with your feet up, and make sure that all's well with bubs.
Good point! I haven't had BP issues while PG but I had mine immediately after & was at threat of going back to hossie... and I stressed out every time they took a reading which was kind of counter-productive
So, relax & rest! its amazing how much it can help, and as Amy said, keep us posted
