chemical pregnancy 

REPRODUCTION MEDICINE

A reproduction specialist term of art for a situation in which a fertilised egg triggers an elevation of hCG–chorionic gonadotropin, but doesn’t implant in the endometrium, passes through the cervical os and is lost.

Its name obtains from the fact that the lack of a gestational sac makes it impossible to confirm fertilisation by ultrasonography.
