What would happen if the zygote did not implant in the uterus?

In brief: Passes out

A non-implanted zygote, like the millions of fertilized eggs in normal physiology that do not implant, will either degenerate or pass out and cease to exist.
The uterus will remain normal and ready to accept another fertilized egg when the opportunity presents itself.

In brief: Debated

It was not a question about when does pregnancy begin? Lol if she were an ivf patient and implantation did not occur you'd tell her nothing happened? That's helpful especially since you weren't there with your micro eyes to see what exactly happened.
I'll stick with early miscarraige thanks for patient understanding.

When pregnancy is established is important as a miscarriage is defined as pregnancy loss-- one cannot lose what is never established. IVF patients who do not achieve pregnancy after embryo transfer are not considered to have had a miscarriage. I think the terminology is important to accurately communicate with patients. This question is more theoretical than clinical; I stand by my full answer.

In brief: Nothing

Pregnancy is defined by implantation not fertilization.
If implantation does not occur after fertilization, the zygote would pass with the menstrual blood. This would not be considered a miscarriage because implantation never occurred.

In brief: Early miscarriage

Period may be a few days late, but nothing exceptional would happen otherwise and no way of ever knowing as period can be late due to many factors.
