'19 Kids' Jessa Duggar Baby Bump Instagram Pic: First Pregnancy Image Released

Jessa Duggar might have just revealed that she was pregnant, but the 19 Kids and Counting star isn't wasting any time before showing off her growing baby bump. Jill Duggar's sister is following her sibling's lead and is taking to her Instagram account to show off her progress while writing how far along she is in weeks and days. Fans of the show might have just learned of the pregnancy, but from the photo that she posted to her social media account it seems that she has had the baby in her belly for about four months now.

That's right, the Instagram photo that she uploaded shows the reality star posing in the mirror with the words "16 weeks 1 day," superimposed in clip art over the photo. Jessa captioned the picture with the same numbers, adding the hashtags "#babybump" and "#BabySeewald."

Jessa has been keeping her fans updated throughout the beginning stages of the pregnancy, which also includes posting picture of her cravings. Radar Online posted that Duggar and her hubby Ben Seewald headed to Arby's the other week to get their fast food fix.

In the image that she posted, she wrote, "Lunch date with my man, Yeah... because 'the baby' was craving Arby's. I love being able to use that excuse."

Jessa opted for the roast beef sandwich that she topped off with a Jamocha shake.

While Jess and Ben were hoping to have triplets, it doesn't seem that she is carrying three kids in her belly, especially since she is maintaining such a slim figure.
