Cheyenne Floyd Is Pregnant! Teen Mom Star Expecting Baby No. 3

Cheyenne shared the news at the end of Thursday's season finale

Cheyenne Floyd Davis and Zach Davis have something major to celebrate.

After sharing their fertility journey on the latest season of  Teen Mom: The Next Chapter, the couple has exciting news to share: they are expecting their second baby together.

Cheyenne announced the news at the end of the finale. She found out via two positive tests just four days before she and Zach were set to start fertility treatments.

Cheyenne also shared the news on Instagram, where she cradled her baby bump in a family video. The event was photographed by Asha Bailey.

"And when we had nothing left to give, we surrendered it all to God," she captioned the post. "We told Him we couldn’t carry it anymore — and He answered. Not in our timing, but in His. This little life is proof that even in the waiting, even in the heartbreak, miracles are still being written."

In addition to son Ace, who turns 4 later this month, Cheyenne is also mom to daughter Ryder, 8, whom she coparents with ex Cory Wharton.

The pair's journey on Teen Mom has shown what a year of struggling to get pregnant did to Cheyenne and Zach, both as individuals and as a married couple.

In a scene where they discuss Cheyenne's sadness as they met with doctors to learn more about what issues they faced, she candidly tells her husband, "I think we need help."

"I think we both definitely want to be married and have a healthy marriage, but I want to feel more connected because I feel like in order for it to work, we have to be transparent and we have to be open rather than just shutting down," she said.

The two debate the merits of the idea, with Cheyenne emphasizing, "We're not at a point of saying, 'We hate each other and we want a divorce. Now let's bring a baby into this to fix our marriage.' We love each other. We want our marriage to be strong and successful, and healthy, for ourselves and for the babies. So I'd rather address it now before it is too late."

Teen Mom: The Next Chapter airs on Thursdays at 8 p.m. ET on MTV
