Your changing body
You are probably feeling quite wonderful now that most of the early pregnancy symptoms like nausea, dizziness, frequent urination and fatigue are gone in week 21. You may be able to feel your Uterus about a half inch above your navel if you place your fingers. You may notice that your lower legs and feet swell towards the end of the day. This is due to the retention of excessive fluid during pregnancy. Try to get plenty of rest.
