Jessa Duggar is definitely glowing!

The 24-year-old Counting On star shared a split-screen photo of herself Thursday on Instagram in which she compared her appearance at 31 weeks during both of her pregnancies.

Duggar's two baby bumps look exactly the same size and it's almost a mirror image, as even her hair is parted the same way and draped over the same shoulder. Duggar is also cupping her baby bump with her right hand in both pictures.

The only noticeable differences? Duggar was wearing a black shirt in one photo and a white one in the other. She also has a different cover on her cell phone.

But the biggest difference is the fact Duggar's current baby bump is lower on her body than her first when she was carrying a boy, Spurgeon Elliot. A few of Duggar's followers therefore guessed the Counting On star and her husband Ben Seewald are expecting a baby girl this time.

The last time Duggar compared her baby bump from both pregnancies was in late October when she was 25 weeks along.

Spurgeon was born November 5, 2015, just about one year after the couple got married.

Duggar and Seewald announced they have a second child on the way in late August. The baby is due in February.
