Your bump is growing steadily. Stretch marks may appear on your abdomen, breasts, or thighs. Varicose veins can develop due to increased blood volume and pressure. You may notice swelling in your hands and feet, especially later in the day. Backache is common as your posture adjusts to the growing bump.
