The Wife is almost out of Gynol II for her diaphragm. Since it expires after for a few months. She doesn’t have an” emergency tube”. It’s more just a rotation. It’s definitely time to order some since few if any stores still carry it. We haven’t had a problem finding it online; but, it’s always a worry until our order actually arrives; especially since diaphragms are so rare. Of course, The Wife’s is still being used frequently which is the way we like it.
