Jessa Duggar looks like she's about to pop! The 22-year-old reality star has been doing an awesome job keeping her fans up to date on the size of her baby bump as her Nov. 1 due date quickly approaches, and her latest photo shows her biggest bump yet. "39 weeks 4 days!" she wrote. "Feeling as big as a barn, and soooo ready to meet by baby! #BabySeewald."

She and her husband Ben Seewald are so excited to be first time parents. Just last week, Duggar posted a photo collage comparing their baby pictures to their baby's sonogram photo, wondering who the baby is going to look like more. "Sitting here dreaming about the moment when we will meet our little one face-to-face..." she wrote.

On Oct. 15, they celebrated her upcoming due date with a family-style fall-themed baby shower, and everyone had such a good time as they played fun baby games and ate pumpkin treats, as HNGN previously reported. "She's looking the part," a source said of Duggar's bump. "She's adorable. She didn't gain any weight in her face at all. She's absolutely flawless."

Take a look above at Duggar's baby bump progress over the past nine months.
