It sounds as though Knox is exhibiting signs of a false pregnancy. Since she was spayed last month, it is not possible for her to actually become pregnant. Rarely, a portion of ovarian tissue (referred to as ovarian remnant syndrome) can remain after a spay, which then produces hormones and can cause signs of heat and possible pregnancy. I do recommend taking Knox to her vet for an exam and to consider blood hormone levels to determine if ovarian remnant syndrome is suspected.
