Both my OB and Perinatologist told me that (significant) swelling in and of itself is not a critera for PE. But it is sign to watch things a bit more closely. In my first pregnancy, I was so swollen, I had to wear my husbands shoes the last month! But the swelling started much earlier, in the 7th month, before the HBP. With my current pregnancy, I have been drinking sooooo much water, I go to the bathroom every 1 1/2 - 2 hrs. I was also told by my nutritionist that dandelion leaf, which you can put in a salad (although its quite bitter), is a natural, mild diuretic. I was able to find some in my supermarket, and try to eat some every few days. So far, I have had no swelling.
Good luck -- hopefully your swelling is nothing serious. Here's to an uneventful pregnancy!!!
