Pitted Edema in Legs

Jodi
So my feet have been pretty swollen, on and off. Which I know is a normal pregnancy discomfort. However, I've noticed that my legs now have "pitting" edema. When you push on the skin, the skin stays indented. It's pretty bad this evening. Is this normal pregnancy stuff too? I took my BP and it's completely normal. Low actually, 103/67. I'm 34.5 weeks. Anyone else experience this??
