20w and may already have preeclampsia. Anyone have advice? :(

2 weeks ago, at my last appointment, my BP was 150/92, which is really high, it's never been that high. So, they told me to monitor it and come back in 2 more weeks to check it again, and to cut out sodium, but not completely. So, I come back and my BP was 119/78!! Which is really good. But the only problem now, is that I had to do a 24 hr urine test & blood work,  because there is more than normal protein in my urine. I also have mild swelling of hands, feet and under my eyes. 
My doctor calls me tomorrow to let me know about my urine test. 
Does anyone have any advice? This is my first pregnancy :(
