First if you made a mess in your pants, you need to get new pants. Seriously, I know that it's nerve-wracking from personal experience, and that you're probably freaking out right now, but I want to help keep you calm if I can, --breathe.
It sounds like your doctors have diagnosed the preeclampsia. And, if she's at home, please monitor her, and if I were you, I'd take her in if she's showing any signs or symptoms of "red flags." I know that they're listed on this website--if you click on "About Preeclampsia" on the homepage, and then click on signs and symptoms, there's a list. But in short, spots, blindness, nausea, bad headaches, high blood pressure. These are what my wife had and the docs made her go to the hospital. My wife didn't work, she was on bedrest (in my non-medical opinion, it helped) and to tell you the truth, given the option she wouldn't have worked.
My wife and twins survived (her preeclampsia hit post-partum). I'm not a doctor and have no magic 8 ball, but hopefully you have a doctor that you totally trust with their lives (hopefully you have a high-risk OB as my wife did), have 24/7 access to medical care (via a nurse or labor & delivery), and know what to look out for for her (my wife got so bad she seemed cognizant at the time but doesn't remember). Take care of her and watch out for her, love her. Fortunately or unfortunately, it's up to us to be calm and reassuring for them. The best we can do is keep an eye on her, watch out for signs and symptoms, call your medical provider if you're concerned at all. Oh yeah, my wife also constantly made sure our kids were moving inside of her.
Arm yourself with knowledge and don't be afraid to act.
Hope and pray for the best...
