There might be a new addition to the Duggar clan as Anna Duggar is reportedly pregnant once more. While the large family remain close-knit, Jim Bob and Michelle have allegedly warned their daughters about their cousin, Amy Duggar.

Anna Duggar might be pregnant again with baby number five. Rumours that Josh's wife is once more with child began swirling when the young mother was photographed clad in a loose-fitting sweater which had people thinking that Anna was trying to hide a baby bump.

Radar Online reported that the 27-year-old believes that she's pregnant again after visiting her husband several times in rehab.

As followers of "19 Kids and Counting" know, Josh has been in a faith-based rehab since August 2015, after the Ashley Madison hack forced him to admit that he had been unfaithful to his wife and is addicted to pornography.

According to reports, Anna is said to believe that the "baby is a sign that God has forgiven Josh for his many sins." It's unknown whether Josh is aware of her current situation, although Jim Bob and Michelle's eldest son is rumoured to have already returned home.

The Duggar parents recently greeted their son on his 28th birthday. Their message was posted on the family's official Facebook page, along with a photo of two of the younger daughters with a cake. This has prompted people into thinking that Josh might finally be home, as it's unlikely that anyone would bake a cake for someone who is far away. There's also the fact that Josh's stay in rehab was reported to be only for six months.

While there's no doubt the Duggars will happily welcome another baby to the fold, it seems Amy Duggar is less than welcome. Reports have said that Jim Bob and Michelle are not too keen on Amy influencing her cousins and had warned their daughters against hanging out with her outside the compound.

Amy admitted as much on Instagram and explained to one fan that "It's a rule though that if I want to spend quality time with them I have to come see them." She added that her aunt and uncle don't want her influencing their daughters but says she doesn't make a big fuss about it.
