Way to go! What a great husband you'll be!! You're already a great fiance and dad!
Relaxing really is key.
When I first came down sick, I had PIH (pregnancy induced hypertension). And for me, it eventually led to a moderate case of PE. I also had really really bad carpal tunnel in both wrists - and I worked as a product manager sitting at my desk typing most of the day - my arms ached so bad I'd be in tears.
Have you gotten a home BP monitor? I know there's a link somewhere here that talks about the "right" way to take a BP measurement - sitting up, both feet on the ground, left arm (not really sure why, but right arm "skews" the readings). Also, if you ever end up in the hospital, make sure they use the proper sized cuff - I'm not a tiny girl, but I'm not a big girl. I usually (usually - not when I was pregnant) had the "regular" sized cuff. Well, the nurses didn't like the readings so they'd switch to the extra large cuff. That also "skews" the numbers.
If I'd known then what I know now (based solely on this board), I would have insisted that they use the normal cuff and document the accurate BP readings. It was my life and my son's at stake. No messing around next time for me!
I also found that some movies, especially with ANY type of tension, would affect my BP.

Hang in there. Make sure you're doing kick counts - there's another link somewhere here for that. ANY decrease in movement warrants a trip into L&D.
You're doing great!
