Just seconding Teresa, in your shoes I'd really want bloodwork today to make sure the pain you're experiencing isn't more serious. Here is a link to a lot of women sharing their different experiences with the URQ pain. viewtopic.php?f=85&t=492
HELLP often happens with PE, but can also occur without high bp or protein, so I'm less reassured that your bp is okay.
As for rest and activity, doctors prescribe bedrest because it seems to make sense, but so far research doesn't support it. After I was diagnosed in my second pregnancy I had one of the busiest days of my entire pregnancy - and my bp rang in super low. I like Caryn's explanation of how it's a "negotiation" between the placenta and mom's body of where the resources go, reflecting in fluctuation symptoms, but the underlying dysfunction doesn't go away.
