The Duke and the Duchess of Sussex have decided to cut Meghan's program "lightly" during their Australasian tour, says Kensington Palace.
Prince Harry was without his pregnant wife when he presented medals to the athletes of Invictus Games on the sixth day of the couple's overseas trip.
Meghan retired after the opening ceremony on Saturday night, which lasted almost two hours.
The Duchess then joined Prince Harry for engagements later in the day.
A spokesman for the Kensington Palace said: "After a busy schedule, the duke and the duchess have decided to reduce the duchess's schedule for the next two days, before the last week and a half of the tour."
The couple, who are expecting a child next spring, have 76 events on their agenda during their 16-day tour of Australia, New Zealand, Fiji and Tonga.
Prince Harry went alone to meet the competitors of the route cycling in Sydney's Domain on day two of the Invictus Games.
At the Games, founded by the prince in 2014, injured service personnel from 18 countries compete in 11 sports for eight days.
The Duke of Sussex later showed his sense of humor while putting on a pair of tight bathing pants, known as budgerigar smugglers in Australia, over his jeans.
Sportscaster Dylan Alcott and two members of the Australian team Invictus Games at Admiralty House, where the royal couple is staying in Sydney, presented him with trunks.
Dylan Alcott, a triple Paralympic gold medalist in wheelchair tennis and wheelchair basketball, said: "We gave him a gift." One of the athletes, Matt (model), gave him a pair of parakeet smugglers. he put them, on his jeans, he looks awesome
"He said:" Do I put them on? "We said:" 100%. "So he put them on. Good for him."
Meghan joined her husband at a reception for Invictus' competitors, their relatives and friends organized by Australian Prime Minister Scott Morrison.
The couple will then travel to Fraser Island, on the Queensland coast, with a visit to Lake McKenzie planned for Monday.
