I had really bad swelling when I was pregnant but my feet never looked bruised - felt like it though! However after I had my DD I remember looking at my feet a few days later and the swelling had gone down but it was like their was a little fluid pocket right next to my ankle bone - it was incredibly sore and was black - looked like a bruise. The only thing that gave me some relief was massages by my hubby, it hurt but afterwards felt better and the fluid eventually went. However because you are still pregnant you may have a while before the fluid goes away!
