Jessa (Duggar) Seewald is ready to welcome her baby into the world.

The reality star, 22, took to Instagram on Thursday to share a picture of herself at the tail end of her pregnancy (39 weeks and four days, to be exact).

“Feeling as big as a barn, and soooo ready to meet my baby! #BabySeewald” Jessa wrote as the caption to the sweet shot of herself with her hand resting on her large baby belly.

The former 19 Kids and Counting star and 20-year-old Ben Seewald‘s first child is due on Sunday, which also happens to be their first wedding anniversary.

Jessa has shared several updates with fans throughout her pregnancy, including several baby bump pictures and, most recently, an ultrasound of her baby alongside baby pictures of herself and Ben in which she speculated that baby Seewald “will be a sweet mix” of the two.

A week ago, the expectant couple released a series of glowing snapshots from a maternity photo shoot on their website.

Jessa recently celebrated her baby shower with a big, co-ed blowout and a source told PEOPLE she is “adorable” and “really excited.”

The event was filmed for her and her sister Jill (Duggar) Dillard‘s upcoming TLC special, Jill & Jessa: Counting On, which focuses in part on how Jessa is preparing for her first child.
