Suggest Treatment For Swelling In Ankles

Hi I am 36+6 weeks pregnant and I have noticed that my ankles appear swollen recently. I have been very active still with not much rest until later at night which is when I notice my ankles. I have no other symptoms. My midwife last week said I had protien in my urine sample but I have heard nothing else from her as she sent away for tests. I am drinking water and today I am having a complete rest day. Should I be worried, do I need to see my Dr/Midwife???
