Congratulations may be in order for Jill and Derick Dillard once more. The couple welcomed their first child, Israel David, on April 6. A new Instagram video posted by Jill, 24, on Saturday had fans abuzz with pregnancy rumors.

The video, uploaded to Jill’s Instagram page, shows her pushing Israel, 4 months old, on a spinning playground structure. According to the video’s caption she, Derick, 26, and Israel were enjoying a little family time in Central America where they are currently on an extended mission trip. As adorable as the mother-son moment was, that wasn't what had fans talking. While Jill circles around with baby Israel in the video it appears as though she's hiding a growing baby bump beneath her loose-fitting shirt. Fans immediately took notice of the possible bump, sending their congratulations in the Instagram post's comments section.

The couple recently took a break from their mission work in El Salvador to return home for the wedding of close family friends Michaella Bates and Brandon Keilen of "Bringing Up Bates." During their trip home on Aug. 14 they were able to spend time with family and friends whom they'd been unable to see for quite some time. Jill and Derick announced their plans to participate in an extended missionary trip in June with a statement that claimed God had "put a desire in out hearts to serve Him internationally." They have returned home for short visits twice since leaving Arkansas for Central America.

It was initially believed that the family's trip would be documented on their hit reality show, "19 Kids and Counting," but that never came to be. The show was canceled on July 16 due to reports that Jill's brother Josh Duggar had molested five young girls at the age of 14. The network's decision came just a few short weeks after Jill and Derick announced their plans. They have made sure to keep fans updated on their trip via social media by sharing pictures, videos and tweeting regularly.

Neither Jill nor Derick has addressed the pregnancy buzz at this time.
