Baby's on the way! Jessa Duggar took to Twitter on Sunday, June 14, to share a pregnancy update with her thousands of followers. 

"#BabySeewald #20Weeks!" Duggar, 22, captioned a baby bump selfie. But Duggar and her hubby Ben Seewald seem more excited about the life growing inside her than the belly itself. 

The 19 Kids and Counting star also shared a video of her sonogram via Instagram, writing, "#BabySeewald is growing fast! Already practicing swallowing, sucking a thumb, and actively moving arms and legs! So excited at the feeling of these first baby kicks! #UltrasoundVideo #20Weeks --with @ben_seewald." 

#BabySeewald is growing fast! Already practicing swallowing, sucking a thumb, and actively moving arms and legs! ???? So excited at the feeling of these first baby kicks! ???? #UltrasoundVideo #20Weeks --with @ben_seewald "For you 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. My frame was not hidden from you, when I was being made in secret, intricately woven in the depths of the earth. Your eyes saw my unformed substance; in your book were written, every one of them, the days that were formed for me, when as yet there was none of them. How precious to me are your thoughts, O God! How vast is the sum of them! If I would count them, they are more than the sand. I awake, and I am still with you." - Psalm 139:13-18

The couple's baby bliss comes after the Duggar family has been under a lot of stress with Jessa's brother Josh Duggar molestation scandal. Jessa has come forward as one of Josh's victims, but spoke out defending her brother in an interview with Fox News' Megyn Kelly

"I do want to speak up in his defense against people who are calling him a child molester or a pedophile or a rapist, some people are saying,” Jessa told Kelly. “I’m like, ‘That is so overboard and a lie really.’ I mean people get mad at me for saying that, but I can say this because I was one of the victims.”
