Meghan Markle has to follow one strange toilet rule when dining with the royal family.

The Duchess of Sussex became an official member of the royal family after marrying Prince Harry. Now that she's a member of the Firm, Markle has to follow certain protocols when she's eating meals and spending time with the royals. According to Christine Younan, a journalist for Daily Star, the members of the royal family are discouraged from "announcing their intentions" when they leave the table. They will just say "excuse me" and leave.

In addition, if they are not yet done with their meal, they should cross their knife and fork. This is to alert the staff that they are not finished eating. In case their plate is clean before nipping to the loo, they must place the cutlery at a certain angle with the handles at the bottom right of the plate.

Markle has to learn the rules in the royal household which include her manner of dressing, food choices and even accessories. According to Myka Meier, the Duchess of Cambridge and Duchess of Sussex are only permitted to wear diamonds during special occasions. There is also a suggested time when they can wear gems.

"Other jewels are worn pre-6 p.m.," Meier said. "Before 6 p.m., you’ll see metallics, gemstones, pearls, sapphires. At night, you’ll see the diamonds come out, and that’s in order to not come across as flashy in your appearance."

Prince Harry and Markle are set to visit Australia, Tonga and Fiji soon. Due to this, many believe that the couple will delay their pregnancy as the countries they are about to visit are affected by Zika virus which is not safe for pregnant women.

"Zika virus has been reported in Tonga. Public health officials have reported that mosquitoes in Tonga are infected with Zika and spreading it to people," a report from the Centre for Disease Control and Prevention stated.

"There is evidence of ongoing Zika virus transmission in Fiji," the International Association for Medical Assistance for Travellers confirmed. "Take meticulous anti-mosquito bite measures during the daytime. Pregnant travellers should postpone travel to this country."

Prior to this, fans speculated that Prince Harry and Markle were already expecting. There were photos of Markle where her breasts and tummy appeared larger than usual. Apparently, it was just due to a gust of wind.
