"Apparently the baby is measuring to be due on May 8, 2020 and no longer May 14th! So we have a new due date!" Jamie, 33, announced on Instagram late last week, sharing a video of Doug and herself following an ultrasound.
On Monday, Jamie took to Instagram to reveal she's actually 11 weeks into her pregnancy and her baby is currently the size of a pumpkin.
"It was at ten weeks with our last pregnancy we found out our baby had no heart beat. It left us crushed. I think it's a gift from our angel baby, God and the universe that the OB gave us a different due date than our fertility doc...which had us practically skipping week 10 of this pregnancy," Jamie wrote.
Alongside Jamie's lengthy post, she uploaded a series of images featuring her two-year-old daughter Henley Grace, who was born in August 2017, in which both girls were wearing matching outfits and had little orange pumpkins painted on their stomachs.
"When week 10 was coming up in this pregnancy I was scared. What if I get bad news again? But I went in to get an ultrasound at what I thought was 9 weeks pregnant and found out that I was practically ELEVEN weeks," Jamie continued.
"Based on the way the baby measured they think we are further along than what our fertility specialist predicted. They gave us a new due date -- May 8th, 2020."
Jamie added, "If you're newly pregnant with your rainbow baby (or even just in general) and 'irrational' fears creep up on ya -- you're not alone. And you're not crazy either. So don't let anyone make you feel like you are."
Jamie currently serves as the host of Married at First Sight: Unfiltered, the show's post-episode discussion show that also airs on Lifetime.
Jamie and Doug additionally appeared on Married at First Sight: Couples Couch, which featured former MAFS couples offering commentary on encore broadcasts of the show's ninth-season episodes, this past summer.
