Cord Coming Off

Is anyone able to tell me if this is a normal look for a cord coming off? He's only a week old so I'm not sure if that's enough time for it to fall off or if it's too early? We tried calling his doctor and had to leave a voicemail but we don't want to put his onesie back over it if it's not meant to fall off yet ๐Ÿ˜•๐Ÿ˜•๐Ÿ˜•
