Eugenie - who wed Jack Brooksbank in October 2018 - made headlines in January when she revealed 2019 would be an exciting year in a cryptic post.
It is believed that the 28-year-old will wait for Meghan Markle to give birth before she makes the announcement.
A source told Vanity Fair: "It’s my understanding that Eugenie and Jack decided some time ago that they wanted to get married, and there was some talk about a wedding in 2017, but they had to wait for Harry to go first."
However royal expert James Brookes told Express.co.uk there are “no rules” stating she must wait.
“As with any pregnancy, I’m sure Eugenie and Jack would want to be sure everything is progressing well after the preliminary scans and let family and close friends know before announcing the news publicly.”
