sounds like you should get another one quick-smart! if you used it a lot anyway, then you'll probably continue to use it in the future, and i'd say it would be worth having it at hand even just for the peace of mind...
ask a good friend, your DH, or your mother to pop out and get you one tomorrow if you don't have the energy. they'll love to help, and you will be feeling fully-equipped for your home birth again.
good luck!!
