They could be reabsored as you mention. It could be a false pregnancy too. Not that common but it does certainly happens now and then...So I took her to the vet this am for an xray and it showed no kittiesI'm kind of sad but in a way it's good because she was so young! She will be getting spayed ASAP. Thanks for all the adevice
Anyways, NOW you know she is OK, and you dont need to wait any longer. Just let the heat be over, and spay her immediately afterwards. Its best so.
