Anyone else spend the night at hospital for bp and 24 hr urine screen?

Blair
I had my routine OB appointment this afternoon, my blood pressure was elevated and for the first time, I had +2 protein in my urine. I was also dealing with a pretty awful headache for the past 2 days. So, doc sent me to the hospital to have my bp monitored and have a 24 hr urine screen for protein in my urine. (I had an ultrasound... baby is happy, healthy and measuring a bit big haha. Blood work came back normal, and my bp has been down since I've been here.) 
**Just curious who else has gone through this and what the outcome was, or what the possible outcomes could be. I'm obviously worried about preeclampsia, and just not sure about what's really going on. Any insight would be appreciated!! Thank you!
