Quoting inluvwitmylittleone*MMM*:" What does the OB mean when they say to watch for sudden swelling? My ankles were not swollen yesterday ... [snip!] ... is normal at nearly 37 weeks. I have been showing NO signs for pre-e. Perfect BP's and urine. What do you ladies think??"
The sudden swelling can mean pre-e. That's why they want you to watch for it. When you push on your swollen ankles, does the imprint stay for more than minute? If so, call your OB. Otherwise I would rest, put your feet up and drink a butt ton of water.
