One huge plot hole

Rating: 9/10 (27 November 2018)

I really love this twisted movie. The performances are excellent, and nobody today can touch subject matter such as this like David Fincher.
Having said that the story, contains at least one huge plot hole. She is supposed to be pregnant when she disappears, yet when she is at the hospital after her return, nobody thinks to run tests to make sure the baby is ok. This would have started unraveling her story because she was never pregnant to that point. Also did the FBI do no investigating at the crime scene at all ?
