Facial swelling, as well as swelling in the hands, feet, or ankles, can all be signs of pregnancy. Swelling, or edema, is a common symptom among pregnant women. Edema of the hands, feet, and ankles typically increases during pregnancy. However, facial edema is common earlier in pregnancy. Again, facial swelling can be a sign of many other things, including inflammation, dehydration, infections, allergic reactions, or facial trauma.
