Among some species, reptiles being one, there is a scenario called Parthenogenesis in which a female having never bred can produce fertile eggs and offsping. The understanding is they are in essence clones of the mother and thus are all female. Its natures way of ensuring existence without access to the opposite gender. You may have to wait and see, but I would look through this forum on a do-it-yourself incubator made from a cooler just in case. Best of luck either way.
