The 22-year-old is expecting her first child with her husband Ben Seewald on Nov. 1 — which also happens to be their one year anniversary. In the photo, Jessa, who is the third daughter born to Michelle and Jim Bob Duggar, is cupping her growing baby bump with the caption, “16 weeks 1 day.”

Jessa also shared a photo as she hugs her husband Ben on his graduation day.

Michelle and Jim Bob Duggar are excited about all of their grandchildren (four so far and more on the way!) and if all of their 19 children have as many children as they have, then there will be more Duggar offspring than the population of California. Really. Check out our chart here to see how the numbers add up.
