Jill Duggar and Derick Dillard's return to Arkansas sparked pregnancy rumors claiming that the Duggar family member is conceiving her second child and may stay longer contrary to what she previously announced in her blog.

The pregnancy reports particularly got heated up in one photo on Sunday where Jill and Derick received a warm welcome at the airport with some members of the clan. In the picture, the 25-year old reality TV star is donned with a high-waisted skirt and a black blouse, an outfit deemed to hide her growing baby bump. She also carried her sister, Josie in her mid-waist as if trying to hide her belly.

The photo immediately arouse the Duggar family's followers on Instagram with one follower asking, "She does look pregnant but is holding Josie to cover it up."

"Jill looks like she might have a baby bump," says another commenter.

"Is she having another baby? Is that why they're going to be home for several months, so she can deliver around family?"

It can be remembered that it was teased in the Counting On trailer that Derick expressed his desire to have another baby and thus sources are now looking at the possibility that the young couple is working on that goal thus their return in Arkansas after a year of missionary work from the Zika-infested region in Central America.

"Let's try to have another baby before next year," Derrick said.

Although Jill and Derick's return will be featured in Counting On, the show is said to focus on Jinger Duggar and her engagement with the athlete, Jeremy Vuolo.

As to whether Jill and Derick will be staying in Arkansas for good, the Duggars announced in their Facebook account that the couple will only be staying for a short period of time and will continue to work on some activities expected by a Duggar including attending "some Bible classes" and "continue to work in ministry from the US."

"We are so thrilled to have Derick, Jill and Israel back home with us, and are so thankful God kept them safe while they were on the mission field. We know they will only be here for what will feel like a short period of time, but we plan to enjoy every second they are here with us!"

Meanwhile, fans noticed Derick's man bun that replaced his long locks.

"Truly love his hair. Be free be yourself."

The man bun was made for you, Derrick!"
