Earlier this week we were given the surprise news that the Duke and Duchess of Cambridge are expecting their third child, after Kate Middleton's acute morning sickness, hyperemesis gravidarum, meant the couple had to reveal the news earlier than anticipated. Her condition meant that she could no longer fulfil an engagement she had planned that day at Hornsey Road Children’s Centre in London.
Now, people are starting to speculate on how far along into her pregnancy the Duchess is, considering the sudden nature of the announcement. Kensington Palace neglected to confirm her due date in its official statement.

While most women wait until the 12-week mark - at the end of their first trimester - to share the news, it is widely assumed that Kate isn't yet at this point. But now her husband Prince William may have let slip on where she is in her pregnancy.
After speaking at the National Mental Health and Policing conference in Oxford yesterday, an audience member congratulated him on the news. William reportedly responded by saying: Thank you, it's very good news. There's not much sleep going on at the moment.'
He continued to say that: 'It was a bit anxious to start with' but that they can 'start celebrating this week' - something which might hint that Kate is approaching the 12-week mark. If this is the case, then the baby will be due in six months time, in mid-March 2018.
Bookies are already taking bets on what the name of the baby will be, with Alice, Victoria and Elizabeth being the most popular for a girl and Philip, James and Arthur for a boy.
The child will be fifth-in-line to the throne, following grandfather Prince Philip, father Prince William, elder brother Prince George and elder sister Princess Charlotte, who will not be passed over thanks to a change in the law of succession.
