It's been only a few days since Jamie Otis announced she had suffered a miscarriage, and understandably, she is still grieving.

The Married At First Sight alum posted a heartbreaking message to her baby via Instagram on Saturday.

"Not a day goes by that I don't wake up thinking of you, Baby Hehner. I know I have to get back to 'normal life' but I just don't know how to," Otis wrote, posting the message alongside pictures of her with husband, Doug Hehner, proudly displaying her baby bump just days before the miscarriage.

"Today daddy and I are going to pick out a perfect name for you," she continued. "We love you so much. I hope you're bouncing on clouds and feeling loved all the way up in heaven." 

The 30-year-old nurse previously opened up about her miscarriage in a blog post where she described being in a state of disbelief. 

"How could the prognosis be so 'poor' when I had just seen our baby's feet kicking and his little body bouncing around in my belly less than a week before," she wrote at the time. "Needless to say, we didn't want to believe in that prognosis even though everyone raved about how amazing this doctor is. (And there's no doubt in my mind he is an amazing doctor, but we were just in such denial!) We decided I would go on bed rest, drink lots of coconut water and even more regular spring water and fight for our baby."

The heartbreaking miscarriage occurred just a week after the couple announced the pregnancy.
