Kate Middleton, 35, and Prince William, 35, announced the pregnancy on September 1.
But like with her previous two pregnancies, the Duchess has been suffering with severe morning sickness, hyperemesis gravidarum.
Kate’s condition has meant she has had to cancel a number of public appearances, leaving husband Prince William to attend them alone.
But despite her absence at events, the Duchess’ pregnancy has not strayed far from people’s minds.
Many have speculated over what the gender of the baby will be and what it will be called.
Its due date was also a topic of discussion, but on October 17 Kensington Palace announce the baby was due in April next year.
One rumour circulating is the couple are expecting identical twins.
But what has Kensington Palace had to say about this?
The report came from life & Style Magazine which claimed Kate is pregnant with now one, but two children.
The publication stated a “palace insider” had shared Kate and William are expecting identical twins and will “soon be a family of six” with their son Prince George, 4, and daughter Princess Charlotte, 2.
But the report has since been denied by Kensington Palace who have pointed to the statement released on Twitter about the baby’s (singular) due date.
It tweeted: “The Duke and Duchess of Cambridge are delighted to confirm they are expecting a baby in April 2018.”
