I'm so sorry you are dealing with this.
If I were you I would definitely go back in Friday, and of course sooner if your wife's symptoms increase or worsen. Those pressures are a significant increase over her normal baseline. Besides repeat testing, I would want some better guidelines from your health care provider on when they want you to call in vs. head straight to L&D if her symptoms worsen. And ask how frequent her appointments should be based on current symptoms. You could also ask them about kick counting: http://www.countthekicks.org
If your wife's symptoms are caused by preeclampsia, delivery is the only thing that will make things better eventually. However, unless your wife's symptoms become severe (such as bad bloodwork results or other symptoms of HELLP syndrome, signs of central nervous system involvement [vision loss, hyprerefflexia, severe headache], trouble breathing due to pulmonary edema, uncontrolled severe hypertension), they will usually try to hold off delivery until 37 weeks. It is a waiting game and a balancing act, trying to determine what is best for mom and baby, which can change quickly based on symptoms and lab results.
Sometimes a bath or even a dip in the pool can help mobilize some of the extra fluid temporarily. For me personally, when I gained several pounds in a day it was a sign of worsening preclampsia. For more signs and symptoms of preeclampsia: http://www.preeclampsia.org/health-info ... n-symptoms
Something you could do at home is buy a home blood pressure monitor. My OB would have me check my pressures morning and evening to help spot any trends.
Please keep us posted as you are able.
