The 25-year-old junior doctor's car was found on Friday 12 February at Ansteys Cove near Torquay, the town where she worked.
A spokesperson for Devon and Cornwall Police said there was "no structured search going on".
However, they said police would continue to perform "intermittent shore line searches".
The BBC understands that a note was found in Dr Polge's car.
It is believed its contents were mainly related to personal issues, but there was a passing reference to Health Secretary Jeremy Hunt.
On Thursday, Mr Hunt confirmed the government would impose a new contract on junior doctors in England.
It is understood Dr Polge had been an active campaigner against plans to change working hours and conditions for junior doctors, and in January posted a new Facebook profile picture, featuring the hashtag #NotFairNotSafe.
Police said her disappearance was "totally out of character" and concerns for her welfare were rising.

Tuesday 16 February - Dr Polge's family release a statement saying they are "overwhelmed" by the support from her friends and colleagues
More than 100 people have been involved in the search operation, including Dr Polge's boyfriend and her family.
A district councillor for the village of Melbourn, Cambridgeshire, where Dr Polge's parents live, said he had no doubt the community would "rally round".
Councillor Jose Hales said: "My heart goes out to the family at this terrible time. The pain and worry they must be feeling is unimaginable."
Police are appealing for the public to contact them with any information or sightings of Dr Polge.

Confirmation of his departure was made in an email to staff on Tuesday.
The 57-year-old, who has headed news operations since June 2011, will be replaced by interim head Peter MacRae.
Mr Boothman has been with the BBC for 30 years and recently oversaw general election and Scottish independence referendum coverage.
In an email to staff, BBC Scotland Director Ken McQuarrie said: "We are now entering the most important period of work ahead of the forthcoming Charter Review discussions as we shape our plans for the future of BBC Scotland.
"I am writing to let you know that John Boothman, Head of News and Current Affairs will be joining the team working on Scotland's proposals for Charter Review.
"Working to Bruce Malcolm, he will play a key role focusing on service development for Scotland including our news offer for audiences for the new Charter period.
"Pete MacRae will take on the role of Head of News and Current Affairs on an interim basis until a permanent appointment is made."
The search for missing junior doctor Rose Polge has been scaled back, almost a week after she disappeared.
