Jessa Duggar Seewald and her husband Ben Seewald celebrated their first wedding anniversary on the due date of their first child.

The 22-year-old reality star and her husband marked the occasion by sharing photos from their nuptials on Instagram. The couple also posted a video of the entire ceremony on their website.

"Our hearts are full of gratitude toward all who worked so hard to make our special day so amazing!" Seewald captioned a photo collage she posted. "Thank you for pouring into our lives, and loving and encouraging us in this first year!

"I promise to encourage you, inspire you and love you truly when we are together and when we are apart; when our lives are at peace and when they are in turmoil; when I am proud of you and when I am disappointed in you; in times of work and in times of rest," she wrote to her husband.

The two married Nov. 1, 2014, and announced they were expecting their first child in April. The reality star is now 40 weeks pregnant, and the anniversary fell on her due date. Duggar Seewald said she ate an entire pineapple in an attempt to induce labor Thursday.

"Cracking up over this one!" the star wrote of an inaccurate tabloid story. "Ben and I were surprised to find out that #BabySeewald was already born last week! I must say, it was certainly a relief for me to find out that all that labor and delivery work is already behind me."

Duggar and her family came to fame on TLC series "19 Kids & Counting," which was canceled in the wake of eldest child Josh Duggar's molestation scandal.

The 27-year-old was further disgraced when he admitted in August to cheating on wife Anna Duggar.
