"30 weeks!!! Baby girl is healthy and non-stop moving this bumpin' belly. I still can't get over how miraculous pregnancy is. I'm so humbled and honored that the Lord would entrust me with this baby to grow, nurture, instruct, and love. Jeremy and I are getting more and more excited to meet her, but also feeling less and less prepared," she captioned the image.

"We are 10 weeks from my due date (August 31st) and we still don't have anything for baby yet — not to mention our house is currently a construction zone — so we are living with my parents (pictured — also currently a minor construction zone). No shortage of excitement and chaos over here."

The happy couple wed in September 2014 after three years of dating. She announced in February that they are expecting their first child together — who we now know is going to be a baby girl!

"I was so surprised. It didn't hit me until I heard the heartbeat at our first doctor's appointment," Audrey told Us Weekly at the time, adding she and Jeremy would like to have "at least four kids."

"We love the idea of a big family," he agreed.

This comes on the heels of Jeremy's brother Zach and his wife, Tori, welcoming their first child together on May 12 — a baby boy named Jackson Kyle.
