But a royal aide close to the Duke and Duchess of Sussex claims that Meghan isn't sick, but just exhausted from the traveling, her demanding schedule and of course, her pregnancy.
The newlyweds are on Fraser Island, where Meghan was seen cradling her baby bump.
The Duke and Duchess of Sussex have landed in Fiji for a three-day visit as their tour of the South Pacific continues.
Harry and wife Meghan Markle arrive in Fiji and inspect the guard.
The news of Meghan's pregnancy had sparked fears among royal watchers about exposure to Zika virus, which is officially listed as a risk in Fiji and Tonga.
The Duchess also pulled out of a string of engagements on Fraser Island, which included meeting with local elders and national park rangers to learn about the Island's natural beauty, rich history, biodiversity and cultural significance and a visit to the pristine waters of Lake McKenzie.
"Thank you for the welcome you have given Meghan and I over the last few days", Harry told the Sydney Opera House crowd.
While Meghan recently took some well-earned rest during the first leg of their tour in Australia, she is thought to be back to her full schedule and planning to attend all engagements.
Their Royal Highnesses have appreciated all of the support they have received from people around the world since their wedding in May and are delighted to be able to share this happy news with the public.
The Duke of Sussex has also stated that many countries including Great Britain look to Fiji to provide leadership on environmental issues which affect all of us, and that have been affecting Fiji as an island nation for many, many years.
But Meghan isn't the only one excited about parenthood. Andrews added that the "Fijian blue" of Meghan's dress is a "tribute to her hosts".
