Mom-to-be Jessa Duggar posted the first photo of her baby bump via Instagram Monday.

“16 weeks 1 day #BabyBump #BabySeewald,” the 19 Kids and Counting star, 22, captioned a mirror selfie cradling her growing belly in a fitted T-shirt.

In April, the reality star announced she’s expecting her first child with husband Ben Seewald, 19.

“We’re expecting!,” she shared. “We are so excited. The due date is November first, our wedding anniversary.” Added Ben: “We are looking forward to being parents.”

Jessa is the third daughter born to Jim Bob, 49 and Michelle Duggar, 48, and her husband is the oldest of seven Seewald children.
