That's the question that's been plaguing Counting On fans for the better part of the past decade.
After all, Jana recently turned 29, but she still lives with her parents and seems to show no interest in starting a family of her own.
Obviously, under most circumstances, there's nothing terribly unusual about any of that.
But Jana is a lifelong resident of Duggar Land, a place where women are repeatedly reminded that they've been placed on this planet for two reasons -- to praise God and to make babies.
Jana's never been accused of being negligent with her praying, but procreating seems to hold little interest for her.
Still, Duggar fans persist in scrutinizing every detail of Jana's personal life for indications that she's involved in some sort of secret affair.
Last month, Jana joined Instagram, which may seem like a very minor development in her life, but was regarded by fans as a sure sign that she'd found Mr. Right.
You see, the adult children of Jim Bob and Michelle Duggar are generally forbidden to join social media until after they've entered an official courtship.
So Jana obsessives were understandably psyched to see that she'd opened an account.
But that hasn't stopped Jana's followers from poring over her every post in search of signs that she's courting.
And this week, the photo below further piqued the curiosity of extremely online Jana-philes.
As you can see, it's a photo of Jana's "quiet little nook," where she presumably enjoys such varied activities as reading the Bible, writing about the Bible, and highlighting Bible passages.
Fans were quick to zero in on the dried flowers hanging on Jana's wall.
Was she saving them because they carried some sort of sentimental significance?
Don't worry, this is social media in 2019 -- a land where privacy and secrets are not permitted -- so many commenters were quick to ask Jana that very question.
"Who gave you the flowers you're saving?" wrote one fan.
Jana was quick to reply, "My brother Jason!"
She added a smiley face and heart emoji, presumably to make it clear that the flowers do indeed represent a fond memory.
That's nice and all, but fans are still rather disappointed by the fact that Jana is not courting Lawson Bates, as had been previously rumored.
Instead, it seems she plans to remain in the nest for the time being, happily sharing a bedroom with her many younger sisters.
Hey, at least Jana's in good company.
She's certainly not the only Millennial who's still living with her parents as the big 3-0 fast approaches.
