Anna Duggar's brief appearance in the recent episode of Counting On, October 11, was startlingly sad. While the episode was focused on Jeremy Vuolo's marriage proposal to Jinger Duggar, Anna Duggar informed the viewers that she is still crying over her husband's cheating scandal.

But there was another speculation that was sparked off by her flash appearance: Is she pregnant with her fifth child?

Anna said nothing about that. She instead said that Jana, her unmarried sister-in-law, has been a tremendous source of comfort. She added that she will miss the 26-year-old if she gets married and moves out of her parents' house.

"Jana has been such an encouragement and such a rock this past year of my life," Anna said. "She is such a treasure, and she will make an amazing wife one day. But selfishly right now, I'm so thankful I've had her as a shoulder to cry on."

Does that mean that the marriage is beginning to splinter? By the end of May, Josh and Anna said that they had a professional marriage and family counselor to "rebuild trust and a truly healthy relationship." But this was two months after Josh finished a six-month stay at a faith-based rehab center.

However, maybe motherhood is her last resort again? Many fans are thinking so, because she seemed pregnant in the recent TLC episode. Perhaps the mother of four is trying to get a fifth baby to save her marriage - which sounds rather a far-fetched way of saving a breaking marriage.

The comments on her Facebook page were fast and furious. "Am I the only one who thinks Anna is sporting a baby bump in tonight's episode?" one viewer wrote on the Duggar Family News: Life Is Not All Pickles & Hairspray Facebook page. 

"I think so for sure," another viewer responded.

One more fan said that Anna seemed thinner when Josh had been away.

After he came back, it was reported that Josh and Anna had gone back to "their normal sex routine." "I would not be surprised one bit if Anna is already pregnant," the insider said, according to Hollywood Life. "I would have hoped they'd have put the brakes on sex after he got out [of rehab], but they are back to their normal sex routine," an insider close to the Duggars revealed to In Touch magazine. "I would not be surprised one bit if Anna is already pregnant." 

It is probably true. In March 2015, when she had been expecting a fourth child, Anna admitted that she already wanted more.

"Some people think I'm not happy unless I'm pregnant," Anna told People. "Marcus just celebrated his first birthday and I was thinking, 'My baby is growing up.' There is a desire to have more children, but also keep the balance of enjoying what God has given you and enjoy the children we have."

Jana Duggar had said in the Counting On show that Josh's family of four children - Mackynzie, seven, Michael, five, Marcus, three, and Meredith, one - are near their parents in Tontitown, Arkansas. Josh is selling used cars, but how does that support his large family?

He is out of TLC, of course. If Anna gets her fifth child, it isn't going to get filmed by TLC. So the TV show as a source of income is out too.

The point is, why is Anna not learning from past mistakes? After struggling with four children and a wayward husband, it does seem rather strange that wants another one.
