"39 weeks, 7 day countdown has started ! πŸŽ€πŸΌπŸ‘Ό #TheBump #BabyGirl," she captioned the snap.

Ensley is Jenelle's third child, as she is already the mother to 7-year-old son Jace and 2-year-old son Kaiser.

In August 2016, Jenelle formally announced via social media that she was expecting a girl. "Time to introduce the world to our baby girl soon, Ensley Jolie Eason," she wrote at the time. The news of the pregnancy wasn't exactly a surprise. A month prior, her secret had leaked out in a police report that stemmed from a small auto accident that David was involved in.

"The passenger in vehicle #1 stated that she is at least (10) weeks pregnant and complained of abdominal pain," a police report of the incident said. "She was transported for treatment to [a local hospital]."
