Time for another baby Duggar update!

Jessa Duggar is now 20-weeks pregnant. The "19 Kids and Counting" star, who is expecting her first child with husband Ben Seewald, took to Instagram to show off her growing belly

The soon-to-be-mommy also treated her fans to an adorable clip of her baby's ultrasound video with the song "World Traveler" by Andrew Peterson playing in the background.

"#BabySeewald is growing fast," she captioned the video. "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. "

In her post, the reality star also quoted Psalm 139:13-18, "For you formed my inward parts; you knitted me together in my mother's womb. I praise you, far 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."

Last week, Duggar shared her first Instagram photo since it was reported that her oldest brother, Josh Duggar, was responsible for molesting five underage girls, including Jessa and sister Jill, as a teenager.
