I'm 19 weeks & 3 days pregnant. i'm having a burning sensation near my belly button. is this normal?

Belly button: It is important to remember that your belly button is not related to your current pregnancy. When you were a baby your umbilical cord was attached to your placenta. Your babies umbilical cord is attached to its belly button. Your belly button is not involved. Umbilical hernias can occur during pregnancy. If you see or feel a bulge around your belly button have your obgyn check it out.
