Meghan Markle has been keeping an exciting secret for the past three months!

Like many expectant parents, Meghan and Prince Harry waited until around the 12-week mark of the duchess’ pregnancy to announce that they are expecting a baby.

After the couple officially made the announcement in a statement via Kensington Palace on Monday, a royal source told PEOPLE that Meghan has had her 12-week scan and is “feeling well.”

The future royal mom found subtle ways to hide her pregnancy over the past couple of months.

Meghan’s royal sister-in-law, Kate Middleton, typically isn’t able to wait until the 12-week mark to announce her pregnancies because she suffers from acute morning sickness, also known as Hyperemesis Gravidarum.

The palace made Kate’s last pregnancy announcement last year within the two-month mark of her pregnancy with Prince Louis because of her illness. When she was pregnant with Princess Charlotte, Kate was also cared for at home at Apartment 1A of the palace. And she got so sick during her first pregnancy with Prince George that she ended up in the hospital for treatment during her first trimester.

Meghan is joining a royal baby boom. In addition to the birth of Prince Louis‘ in April, Kate’s sister, Pippa Middleton, is expecting the birth of her first child this month.
