"First baby bump pic," Jamie captioned the cute picture in which she was lifting up her coral knitted sweater. "8 weeks yesterday!! We are so excited to be growing our family!!"
Jamie revealed her baby is currently the "size of a raspberry," and she added the following hashtags: "#pregnant #8weeks #babyonboard #sizeofraspberry #blessed #grateful #thankful #love #growingfamily #family #blessings #firstbumppic."
The happy pair are already parents to a beautiful daughter, Henley Grace, 16 months.
"Henley's going to be a big sister. Something we've been trying for a while has finally come to fruition and I can't wait to meet our little baby boy," Doug said, according to People.
Jamie then reportedly pointed out, "Yeah, you hope it's a boy."
Jamie went on to say her pregnancy experience thus far has been challenging, as she's been feeling "nauseous" and can "barely keep [her] eyes open." However, Jamie reportedly gushed about how she is "so excited to grow [their] little family."
Jamie and her husband were unable to have sex for quite some time because the act was painful for Jamie after welcoming Henley into the world in August 2017.
The reality TV stars had an arranged marriage and tied the knot in March 2014. Their wedding was documented on Season 1 of Married at First Sight, and their road to falling in love with each other was a bumpy one.
The couple, however, managed to work through their issues and stay together.
And then in July 2016, the pair announced they had endured a heartbreaking miscarriage with their first child. Jamie and Doug called the baby boy they had lost four months into Jamie's pregnancy Johnathan Edward.
