Last week's episode of "19 Kids and Counting" announced that 18-year-old Josiah Duggar is courting 17-year-old Marjorie Jackson. The Duggar family also teased another big announcement for this week's episode, and many people speculate it will be that Jessa Duggar Seewald is pregnant.

On April 12, country singer Mark Wills inadvertently added fuel to the pregnancy speculation when he revealed on Facebook that he met Jessa and Ben Seewald at the Grand Ole Opry in Nashville, Tennessee. He posted a picture of him, Jessa and Ben along with the caption, "Last night at the @opry, I ran into the newlyweds from TLC 19 Kids and Counting. A very sweet young couple."

Soon, Wills Facebook page was bombarded with comments from "19 Kids and Counting" fans analyzing Jessa Seewald's stomach for a baby bump.

"She had a perfectly flat stomach. I see a small pouch and her boobs look wider," a fan wrote. "They only grow towards your armpits when you are pregnant."

The April 21 "19 Kids and Counting" episode "European Honeymoon" focuses on Jessa and Ben's honeymoon to Paris, Rome and Venice. Fans will get to follow the newlyweds as they sightsee through Europe.

If you want a sneak peek of where the happy couple traveled, you are in luck. Five months ago, a viewer named nancykatherinem on Instagram posted a picture of Jessa and Ben at the Eiffel Tower. She ran into them again at Notre Dame where they posed with her for a picture.

"Such a cute and sweet couple. It was so crazy to pass them at the Eiffel Tower and see them again at Notre Dame!" Happy Honeymoon to them! #Paris #cityoflove #duggarfamily," she wrote.

Since the episode focuses on the couple, it would be an ideal time for Jessa to announce that she's pregnant even though she did not conceive while on her honeymoon.

Do you think the big announcement is that Jessa is pregnant?
