About edema. Girls, hi!)) Can you tell me, is edema in pregnancy normal? Like the body is preparing for childbirth… My hands and fingers are swollen, and my feet are swollen too. The tests are good. The doctor said to limit fluid intake. But I'm afraid of edema of organs. How can I understand if I have strong edema or within the norm?
