My foot is so swollen it's actually starting to scare me. It's even leaving indents. My other foot is swollen too but not that bad. I didn't even do any walking. I walked from downstairs to upstairs. And now I'm sitting on the glider while my fiancé builds baby stuff. My feet have NEVER swelled like this. I know it's a normal pregnancy thing but it just seems really out of control. This horrible swelling only started yesterday. Should I call my doctor or stop over reacting? I just have a feeling something's wrong..
