Umbilical cord

My baby is 6 days old and her umbilical cord is hanging on by a thread is this normal I’m worried this is so early for it to be falling off, she won’t see her pediatrician for another 2 weeks and I don’t wanna bring her in earlier than then if nothings wrong. It’s not leaking any type of fluids maybe a little bit of yellow but it doesn’t look serious it’s just hanging on by a little piece
