Pitting edema?

Delaney
I'm 36 weeks tomorrow and noticed my legs and feet looked a little swollen and when I pressed on them it leaves an indent. I called a nurse at the labor and delivery and she said as long as my blood pressure is ok then it's fine. I check my blood pressure every day and it's been normal. I can't help but feel anxious about getting pre eclampsia because my mom had it. Anyone else have pitting edema?
