Meghan and Harry have just returned back to London from their 16-day first major royal tour, visiting Australia, Fiji, Tonga and New Zealand as part of their trip.
Meghan is understood to be almost four months pregnant as the Duke and Duchess of Sussex await the arrival of the latest addition to the Royal Family.
Meghan is expected to go on maternity leave following the birth of her baby, as was the case with Kate, the Duchess of Cambridge, but it is unclear whether Prince Harry will do so as well.
Royal expert Richard Fitzwilliams believes the prince will go on paternity leave as "Meghan would want it too".

He explained how Harry would be able to form a "bond" with his new child, if he decides to take leave from royal duties to spend more time with his wife and baby.
Mr Fitzwilliams told Express.co.uk: "I would certainly expect Harry to take paternity leave as it gives him a unique opportunity to bond with the new baby and I feel sure Meghan would want it too."
Harry's brother, Prince William, took paternity leave after all three of his children - George, Charlotte and Louis - were born.
When Prince George was born, William took leave off his job as a Sea King helicopter pilot at RAF Valley in Anglesey.
