According to one of her most recent social media updates, Jessa Duggar was 34 weeks pregnant approximately two weeks ago.
We're no mathematicians at The Hollywood Gossip, but by our calculations, that makes her about 36 weeks pregnant now.
The average pregnancy lasts 40 weeks beginning from the day of the woman's last period, though the date of conception is usually about two weeks later.
All of this is a very long, unnecessarily scientific way of saying Jessa's due date with her second child is fast approaching this winter.
In all likelihood, it's still several weeks away, but there are some Duggar fans who believe Jessa may be just about ready to pop imminently.
Why would they say that despite what she says online?
This theory seems to be based on little aside from the fact that Jessa concealed her second pregnancy from the media for most of her first trimester.
We're not sure why that would lead fans to believe that she actually got pregnant even earlier and kept it a secret even longer, but hey.
Our motto at THG is that we report the nonsensical rumors that are running rampant in Duggar circles, and you decide if they're total BS.
Okay, we guess there is one other thing adding to the speculation, which is the fact that Jessa hasn't posted anything on Instagram in four days.
We know what you're thinking:
Who the hell cares?
And we believe you're absolutely right to think that, but there are others who believe that Mrs. Seewald's absence from the 'Gram is curious ...
The Jessa pregnancy truthers point out that Jessa usually posts on social media about once a day, which is more or less accurate.
Still, it's a bit of a stretch to say that a four-day stretch is evidence that she's already given birth to a little brother or sister for Spurgeon.
(We imagine its name is Pubert, or something similarly horrendous, but that's a discussion for another time - perhaps soon!)
Maybe they're right, and the reason that her lack of selfies this week must mean that a new life is about to come into the world.
Perhaps Jessa has at least begun this magical process.
She's already surrounded herself with hay and farm animals in a three-walled manger, or however the Duggars prepare to give birth.
Obviously, this is a bit of a stretch. Or a lot.
Still, it's worth noting that Jessa and her fellow female family members do tend to be pretty secretive about their pregnancies.
We guess they don't have much choice.
When 100% percent of your income comes from a reality TV show centered entirely around weddings and births, and you're not not allowed to get divorced, well, you gotta play this as close to the vest as you can for maximum impact.
It's a small price to pay for making a living?
