Astrid Loch and Kevin Wendt have a lot to celebrate.

The Bachelor in Paradise couple revealed they're expecting their second baby together on Tuesday, celebrating Wendt's birthday a day early after finding out the exciting news, which Loch shared on her Instagram Story.

"BABY DADDY times two," the 32-year-old former reality star captioned a black and white photo of Wendt holding a birthday cake with the candles lit. "Test results came back POSITIVE so we're celebrating @Kevin.c.wendt birthday a day early."

Recently, Loch — who already shares 14-month-old son August with Wendt, 39 — opened up about this leg of her fertility journey in an Instagram post.

"Let's take a cute picture to announce," she wrote at the beginning of the photo before sharing the reality of what went down.

Sharing an ultrasound photo earlier this month, the BiP alum shared explained in the caption that it was "not a pregnancy announcement (yet)."

"But today was transfer day so we're holding our breath and keeping our fingers crossed. Last time this all felt much harder to share, there was so much more fear. But you guys have been an incredible community so this time I'm taking you along for the ride," she wrote.

Explaining that the "first pic is little embryo chilling," she then reference the second and third photos in her post, which showed a "glimpse at the meds and injections."

Loch concluded the post with a sweet video, which shows the "moment our embryo was transferred."
