Fluid Retention (oedema) is a problem for many particularly in the last 10 weeks of pregnancy, when half of the extra 3-6 litres of fluid common to pregnancy is retained.
Generally it is not a serious problem unless it is accompanied by elevated blood pressure or protein in the urine. If these accompany it it could be an early sign of toxaemia.
You should have your blood pressure and urine checked.
