As one Duggar gives birth to a baby boy, another Duggar is on its way. It is another exciting time for the TLC's '19 Kids and Counting' stars especially for Jessa Duggar who just recently posted her first baby bump photo on social media.

The countdown finally starts for Jessa Duggar-Seewald who posted her first baby bump photo which her sister Jill Duggar previously did during her pregnancy journey with husband Derrick Dillard and apparently its Jessa's turn to update her followers on her pregnancy journey.

She posted the sweet photo of herself wearing a fitted t-shirt while holding her small baby bump on Instagram writing, "16 weeks 1 day #BabyBump #BabySeewald," she wrote on Instagram mentioning a hashtag Baby Seewald as her husband is Ben Seewald.

Jessa's baby bump is noticeable on second look as she is only just a month long and can obviously still fit in her jeans as seen on the photo she posted. It would seem like Jessa is as excited as her sister Jill as she finally posted her first baby bump photo which her followers wish to not be the last one.

Meanwhile, Jessa also previously updated everyone of how her pregnancy is doing lately and well, fans have nothing to worry about since she is reportedly doing well. Apparently, Jessa "thinks it's a boy," and that her "pregnancy's going great," she previously said in a statement.

Jessa also reports that she is excited. I'm feeling good," she said in her interview for the show. "I'm looking forward to the second trimester," she added. Well, hopefully everything will continuously go great for Jessa and Seewald as the two are obviously excited in seeing their little one or little ones.

The two previously teased their fans about the possibility of having twins in a previous video they posted. "Can't wait to find out if it's a boy or a girl," Seewald said in the clip adding, "It could be both, who knows?"
