Wire fell out of the back of my braces!?

i noticed today that the wire isn't connected in the back (the piece that holds the wire after the last bracket) also the colored band on the last bracket broke off. I don't feel the wire poking me any where and it's not bothering me. My mother is calling the orthodontist on Monday, since they aren't opened this weekend. I was wondering if there is anything I can do to keep the wire in place. I do have a full container of wax left. Thanks in advance!
