I'm so sorry for the loss of your first pregnancy. Totally not doc me, says no matter when your high BP started, those numbers you are having today are high. For an official diagnosis of pre-eclampsia you need the high pressures that you're having as well as protein in your urine, 300 in a 24 hour catch. Though, again, regardless, that's pretty high BP to have and I'm glad to hear they've already tried bed rest and frequent monitoring of baby.
In our 3rd pregnancy our BP spiked early (before 20 weeks) so when protein went over 300 later we were considered "super-imposed" pre-eclampsia since we had high blood pressure earlier than 20 weeks... folks more familiar with all the diagnosing will probably chime in with more detailed information.
With so many people involved with your care you'll probably want to find out who is going to be your go to as well as what your call in numbers are... so for instance, at what BP point do they want you calling or going to L&D. And again, regardless of what label they decide to give you, I think what is important today is you feel comfortable and confident in your plan of action and your team. And trust your mommy gut, if you're not feeling right it doesn't hurt anything to give a call and get peace of mind.
