Swelling, you're thoughts?

Courtney
Hey yall, this is my second pregnancy {33 weeks, 6 days}. But with my first I had absolutely no swelling. So this is a new symptom for me! I had been sitting on the couch for about an hour and a half and i kept feeling like something was right with my left foot, and finally wheni got up to pee and was walking I realized my left foot was pretty swollen.. But my right one was barely swollen. Of course it's very uncomfortable, I wouldn't say painful though. Anyone else had this? And is it normal? I shouldn't be concered? Thanks ladies!
