May 19, 2015 02:42 PM EDT

"19 Kids and Counting" star Jessa Seewald recently shared a photo of her growing baby bump and expressed her eagerness to enter into motherhood.

The 22 year old Duggar daughter, who married Ben Seewald on Nov. 1 and announced her pregnancy in April, posted an image along with the caption, "16 weeks and 1 day #babybump #babyseewald." In the photo, Jessa is shown cradling her rapidly-growing bump with one hand and looking into a mirror.

A short time earlier, Jessa posted a photo revealing her baby's growth while inside the womb and announced that she had reached a major milestone in her pregnancy - 100 days. She captioned the photo, "So awe-inspiring to read about #BabySeewald's growth from week-to-week! #16Weeks "For You [God] formed my inward parts; You knitted me together in my mother's womb. I praise You, for I am fearfully and wonderfully made. Wonderful are Your works; my soul knows it very well." - Psalm 139:13-14."

Unlike her older sister Jill Dillard, who regularly shared pregnancy updates prior to her son's April 6th birth, Jessa rarely posts photos of her baby bump. However, in April, she shared a photo of herself holding her small bump while standing next to her expectant sister-in-law Anna Duggar, 26, who is due in June, and then-heavily-pregnant Jill.

Meanwhile, on Tuesday, the the "19 Kids" star took a moment to wish her husband of six months a happy birthday in a lengthy Instagram post.

"Life with you is always so fun and exciting!" she wrote. "I love your passion for bringing help to the hurting, and sharing with the lost the Gospel of Jesus Christ. Every day you inspire me to be more committed to the Faith. There is no one else I'd rather run alongside in this journey of life!"

The soon-to-be-mom also revealed her "favorite things" about her "dream man," writing:

"You are so tender and compassionate, humble, loving and faithful. You always look out for my comfort and wellbeing before your own. You're not afraid to admit your mistakes and quickly make things right. You're a true gem. With each day that passes, I realize more and more just how blessed I am to have you as my man! There is no one else I would rather have as the daddy of my baby!"

Season 9 of "19 Kids and Counting" ends onTuesday, and TLC is airing a marathon of the Duggar family show in honor of the event. The marathon will conclude with two new episodes of "19 Kids and Counting." "Duggars Guide to Love" premieres at 8 p.m. EDT and "Digging In With the Duggars" will air at 9 p.m. EDT on TLC.
