Kensington Palace officially announced the pregnancy of Kate Middleton, Duchess of Cambridge, through a press release Monday morning. The confirmation said, “The Queen and members of both families are delighted with the news.”

The announcement also said that the Duchess will no longer carry out her planned engagement at the Hornsey Road Children’s Centre in London because she is suffering from Hyperemesis Gravidarum, a condition wherein a woman is experiencing sickness and nausea due to pregnancy.

This will be Kate and William’s third child after Prince George, who is now 3 years of age and Princess Charlotte, who is 2 years old.

Prince George is set to start school this month in London.

According to reports, Prince William’s wife is understood to be less than three months pregnant. But Kensington Palace has to make an official announcement because of Kate’s condition.

Kate pregnancy rumors

Talks about Kate Middleton pregnant with her third child actually started way back in June.

According to a report by Life and Style Magazine, the Duchess was seen at a charity visit at King’s College Hospital on June 12, wearing a blue skit suit with a slightly rounder midsection.

The royal couple, however, decided not to make public the news just yet. Kate was said to be thrilled with the prospect of a third baby and Prince William was just “dying to tell all of his friends and family.”

Hyperemesis Gravidarum

Similar to her two previous pregnancies, Kate Middleton, 34, suffers from a pregnancy related condition known Hyperemesis Gravidarum.

According to medical experts, this is extreme sickness and nausea during pregnancy. It means vomiting a lot, according to doctors.

However, Hyperemesis Gravidarum, according to physicians, is different from the common sickness and nausea being experienced by most pregnant women. This condition, which according to data, affects around 1% of pregnant women is a much more serious case because regular vomiting will run throughout the day, sometimes up to 50 times.

The pregnant woman will also have the inability to keep down food and drink, according to doctors.

Finally, the condition can last right up until the baby is born, medical experts said.

Line of Succession

Kate and William’s third child will become fifth in line to the throne regardless if it’s a boy or girl. This was made possible because of the recent change in Britain’s law of succession. Before, if Kate gives birth to a boy, he would jump ahead of Princess Charlotte in the order of inheriting the English throne.

Prince Harry meanwhile will be down to sixth in line to the throne.
