Josh Duggar's wife, Anna, is pregnant with her fourth child, the “19 Kids and Counting” star announced on her Twitter account late Tuesday night. The announcement follows several pregnancy rumors following a pregnancy test she took in last month’s episode of the TLC reality show.

Anna and Josh, both 26, also announced the news in a video posted on TLC’s website. In the video, Anna revealed that she shared the news of her pregnancy with the Duggar family when they all were together in Arkansas, following Jessa Duggar and Ben Seewald’s wedding last month. The couple also said in the video that the reality series will be returning in February 2015.

"I am nine weeks pregnant and I'm having a lot of morning sickness, so it is difficult, but it's good because I know that good things are happening," Anna said in the video.

After the pregnancy test last month, Anna announced that she was not expecting a fourth child. However, a video that Anna and Josh shared on Thanksgiving Day yet again fueled speculation about her pregnancy as she was seen wearing an oversized cardigan, which seemed to be an attempt to hide her stomach.

The couple have three children, Mackynzie, 5, Michael, 3, and Marcus, 1, with the youngest being born on June 2, 2013.

Josh and Anna had claimed earlier that they wanted to follow in the steps of Michelle and Jim Bob Duggar and have as many children as God would allow.

“We’re really just going to take it one at a time. I don’t think you can say we’re going to set out and say we’re going to have five kids or four or three. We have no control over that. God has the control,” the couple had reportedly said earlier.

Meanwhile, Jill Duggar and her husband Derick Dillard are expecting their first child, a boy.
