Ack! If I read your siggy right, you're diagnosed with PE and there's been no updated bw?! I think I'd want that right away. Once we were diagnosed we did weekly 24hrs/bw.
I had terrible upper back/side pains with my first, it turned out to be "normal" pregnancy related... back managing the growing (in our case too quickly growin) belly. I'll keep fingers crossed it's normal pregnancy stuff... are you on bed rest? I remember that being anything but restful and making everything hurt!
