Kate Middleton and Prince William will be traveling to Pakistan this week for their first tour after their summer vacation. There are speculations that the Duchess of Cambridge will announce her fourth pregnancy while she’s in the country.

According to New Idea, royal fans are confident that Prince William and Kate will make the surprise announcement while they’re on tour. Prince Harry and Meghan Markle did the same thing immediately after they arrived in Australia last year.

But as of late, all three of Kate’s pregnancies were announced while she’s back home in London. Since she suffered from hyperemesis gravidarum during all three of her pregnancies, Kate was unable to perform her royal duties during her first trimester.

According to experts, if the mom of three will have another baby, it’s almost guaranteed that she will suffer from extreme morning sickness again. And if this is the case, it’s unlikely for Kate to be able to go to Pakistan with her husband.

As such, the claims of the publication should be taken with a grain of salt. But there’s no denying the fact that another addition to the Cambridges’ growing household will be delightful news to royal fans.

On Twitter, they have been speculating on Kate’s fourth pregnancy. They are also convinced that Prince William’s wife has been dropping major pregnancy clues throughout the past couple of weeks.

For instance, Kate has changed her hairstyle more than twice ever since she first stepped out in public last month. Weeks later, she changed her hair color to a lighter shade.

Royal fans said that it’s common for Kate to change her hairstyle and hair color shortly before she makes a pregnancy announcement. Other royal fans are also convinced that she sported a growing baby bump months ago. But if this is the case, Kate should’ve already given birth by now.

And during one of her outings, royal fans claimed that Kate felt broody at the sight of kids. But when they asked if she’s planning on having another child anytime soon, the Duchess of Cambridge said that Prince William will be worried.
