Jana Kramer shared the first-ever picture of her growing baby bump in a post to social media on Saturday (Sept. 5).

The country singer and actor posed in profile outside of her tour bus, revealing a small, but clearly visible baby bump with the caption, "It's official. I have popped! First baby belly pic! #18weeks."

Kramer married football player Michael Caussin in May after a whirlwind six-month engagement. The couple announced they were expecting their first child in August, and revealed their baby is a girl later that month.

Though they've been married only a short while, they didn't have an initially easy road to becoming parents.

“We met with doctors and went through some not-so-fun stuff,” the singer writes in a blog for People. “Without getting into detail, it was a very stressful time for something that is supposed to be fun! My heart goes out to the women who struggle with conceiving.”

Kramer is set to release her next album, Thirty One, on Oct. 9. The collection holds a very personal message for the singer, who turned 31 in December.

“In my mind, 31 shows strength, confidence and grace,” she tells USA Today. “That’s exactly who I feel like I am as a person and what I’ve been through in my life.”
