Hey Sallymarie, I'm so with you on not knowing what's high BP! I had it towards the end of my pg, and they did explain the numbers to me but I'm blowed if I can remember what its all about, LOL. They told me to look out for the symptoms that Alan told you, and a couple of times I came in to the hossy for a few hours (like maybe 3-4) and they monitored me every half-hour or so, and monitored bubs with the CTG. Each time, my BP was just fine after the first half-hour! I didn't consciously feel afraid or excited while they were taking my BP (the old 'white coat' syndrome) but aparently there was something going on there.
Anyway, the point of my ramblings is that hopefully you're in the same boat and if you can get monitored for a while as you relax, perhaps you'll find a different result?
