Meghan Markle's recent outing with Prince Harry triggers the rumors that she's already pregnant.

The Duchess of Sussex stuns in her blue sleeveless dress designed by Taiwanese and Canadian designer Jason Wu. She paired her ensemble with matching blue satin pump and accessorized with a small navy Dior clutch.

Markle dissed her signature messy bun hairstyle with loose curls that really looked great on her. However, many noticed that the former "Suits" star's breasts and tummy appear to be bigger than usual which triggers the rumors that she and Prince Harry are already expecting.

"Her breast seems bigger and she appears to have a little bump," one fan commented.

"Saw it too," another user agreed.

"And I think she is pregnant," Ayesha Abbasi wrote.

Meanwhile, the guidelines from the National Health Services suggests that it's better for Prince Harry and Markle to wait as they have royal engagements abroad next month and it's risky for pregnant women to travel. Although expectant moms are not prohibited from traveling they are advised to take caution as the first three months have a higher risk of miscarriage. Also, being on the road for more than four hours can also increase risks of small blood clots or deep vein thrombosis.

In related news, Myka Meier suggested a way to spot if Markle is indeed pregnant. According to her, royal fans should check on her hair as the actress has natural curls.

"The one thing that might be interesting is her hair," Meier said. "We don't know what she does to treat her hair now but it is likely she uses a keratin or a Brazilian treatment to straighten it."

"As soon as she gets pregnant she will no longer be able to use those same products, which could be very interesting. I use the same products because I am quarter African and have very curly, frizzy hair and when I got pregnant I had to stop using all of those," Meir added.

If Markle won't use hair straightening products, she will likely wear her locks in a bun. Surprising, last night she didn't sport her signature hairstyle but had her hair curled.
