Jamie Otis is loking healthy and happy!

The 30-year-old Married at First Sight star Instagrammed a pic of herself showing off her bare baby bump at 15 weeks, and says that all is going well with her second pregnancy. Jamie and her husband, Doug Hehner, suffered a heartbreaking miscarriage last July.

"I truly haven't been overly worried with this pregnancy," Otis writes. "I think bc it has been completely different than my first. I've felt confident this baby will grow safe and sound inside me ... I haven't had any spotting, bleeding or clots so I've felt like I am having a healthier pregnancy this time."

"We lost our angel Johnathan at 17 weeks, 1 day," she adds. "I just want to get past 17 weeks and feel this baby move. I want to know our sweet baby is safe, healthy, and happy growing inside me. Being pregnant is one one of the most joyous experiences, but it's also one of the scariest. #growbabygrow #babyhehner #prayingforhealthybaby #marriedlife."

Otis is due in August. She announced the news that the couple was expecting again last month, and paid tribute to the son they lost.

"We love him so much and are so happy to know he's looking down from Heaven taking care of his little sister/brother," she Instagrammed.

Clearly, Hehner is ready to be a father.

"My beautiful wife with her #excitedface. ...So happy to be a daddy! #marriedlife #pregnant #babybehner #mylove #excited #sohappy," he recently Instagrammed alonside a pic of a smiling Otis holding up her ultrasound pic.

"I've realized that there are SO many women who have experienced a similar loss and feel so isolated from it," Otis told ET. "It wasn't until I blogged [that I realized that] so many women feel the same way as me. It's taboo to share photos and talk about miscarriage."

"I really want to desensitize this topic," she added. "I want to show [other women who have miscarried] that they aren't alone, and I want to give them a space where they can share their sweet baby who was taken from the world too early. I hope by me sharing my story and my son, Johnny, it helps women who have gone through similar circumstances or who are going through a loss now."
