Jessa Duggar has shared a photo of her enormous baby bump on Instagram.

The 22-year-old reality star is nearly 40 weeks pregnant with her first child by husband Ben Seewald. The couple married in November 2014, and announced they are expecting in April.

"39 weeks 4 days! Feeling as big as a barn, and soooo ready to meet my baby! #BabySeewald," she captioned the picture. Healthy babies are typically born between 39 and 40 weeks, and the mom-to-be expects her son or daughter to be born Nov. 1, her first wedding anniversary.

Duggar and Seewald celebrated the impending birth with family and friends at a co-ed baby shower earlier this month. The couple filmed the party for the star's forthcoming TLC specials, and Duggar is expected to also film her baby's birth.

She and sister Jill Duggar are slated for the three-part special Jill & Jessa: Counting On. The siblings appeared in an emotional preview for the show this month, with Duggar admitting her family was "devastated" by brother Josh Duggar's recent scandals.

Duggar and her family came to fame on TLC series "19 Kids & Counting," which was canceled in the wake of Josh Duggar's sex abuse scandal. The 27-year-old admitted to molesting five girls, including Jill and Jessa, as a teen, and later confessed to cheating on wife Anna Duggar.
