Rumor has it there may be another baby on the way for Josh and Anna Duggar. While Josh has been away at a faith-based rehab in Illinois for several months, one report is suggesting his wife, Anna, may be expecting baby No. 5.

While the Duggars have not confirmed the pregnancy, Life & Style reports the former “19 Kids and Counting” star believes she may be expecting. “Anna announced that she thinks she is pregnant again,” a “family insider” told the magazine, as reported by Radar Online. “She believes the baby is a sign that God has forgiven Josh for his many sins, and she’s vowed to stand by her husband.”

Josh, 27, entered treatment in August after he was revealed to have used the affair-facilitating website Ashley Madison. “I have secretly over the last several years been viewing pornography on the internet and this became a secret addiction and I became unfaithful to my wife," the father of four said in a statement. While Josh has yet to return to his family in Arkansas, Anna, 27, has been spotted visiting her husband of seven years at the facility on several occasions, most recently over the Christmas holidays. "Everyone just had fun and seemed to be high spirits, including Anna," a source told People magazine of her latest visit. 

As of Thursday afternoon, the Duggars had not responded to the pregnancy report, which was released Wednesday. The last update on the Duggar family’s official Facebook page included a throwback shot of their daughter Jordyn at age 4. Michelle and Jim Bob Duggar have also updated on their children Jill Dillard, Jana Duggar and John-David Duggar — the twins celebrated their 26th birthday Tuesday — in recent days, but have not given any updates on their eldest son Josh and his family.

The rumored pregnancy comes at a difficult time for the reality TV couple. Josh's admitted affair was his second scandal of 2015 — he was revealed in May to have molested five underage girls, including some of his siblings, when he was a teenager.

He is also currently engaged in a legal battle with adult film star Danica Dillon, who claims he sexually assaulted her during their alleged consensual sexual encounter in March. In a $500,000 lawsuit she filed against Josh, the 27-year-old accused him of being “too rough” during their meeting and says she felt as though she was “being raped.”Josh responded to the allegations earlier this month, saying he never had sex with Dillon and was not in Pennsylvania during the time of their supposed affair.

While the unconfirmed pregnancy might not come as the best time for the couple, Anna has made it clear she wants her marriage to work. "In my heart, when I got married, I vowed to God first and then to Joshua, 'For better or for worse. 'Til death do we part. I pray that through all of this that I would be an extension of God's love to Joshua, that I would love him and forgive him and wait patiently and allow God to work through our hearts,” Anna said during an appearance on TLC’s Duggar spinoff, “Jill & Jessa: Counting On,” last month.

Josh and Anna welcomed their newest addition, daughter Meredith Grace, in July. Their other children are Mackynzie, 5; Michael, 4; and Marcus, 2.
