Rumors about the alleged pregnancy of "19 Kids and Counting" star Jessa Duggar are being given more weight as more "evidence" surface online. 

InTouch Weekly spotted a Twitter post by an alleged fan of their family's hit reality show claiming that she saw the 22-year-old newlywed browsing through the contents of the maternity and juniors section at the Ross in Rogers early this month. 

However, the said "evidence" may not be substantial enough to prove that she is indeed pregnant, since the alleged sighting happened before her sister Jill gave birth to Baby Israel David Dillard. She could just be shopping for a roomier dress for her sister who was delayed in giving birth. 

Still, there are several other sightings suggesting that Jessa is pregnant. 

One of them is the photograph wherein her husband Ben is holding a big cowboy hat, presumably to hide her tummy. Then there is another picture which clearly shows a hint of a bulging baby bump. But there could be valid explanations for the photos aside from her alleged pregnancy. 

The newlyweds were married in a big wedding ceremony back on Nov. 1, which was attended by at least 1,000 guests. They were embroiled in several pregnancy rumors ever since, especially since Jill announced her pregnancy just a few weeks after her own wedding on June 21. 

If Jessa is indeed pregnant, her child will be the sixth grandchild of Jim Bob and Michelle Duggar. Their eldest son Josh currently has three children with wife Anna named Mackynzie (5), Michael James (3), and Marcus Anthony (1), and they are expecting to have a new baby girl in July this year. Jessa's baby boy with husband Derick Dillard was born on April 6. 

Jessa and Ben earlier claimed that they want to start their own family as soon as possible, and are also considering adoption.
