Jamie, 32, revealed an app on her phone informs the couple when they should try, and she joked her husband wants to "hack" into it so that every day appears to be a fertile one.
"It's really funny. Sometimes I'll be like, 'Okay, this is the day, peak fertility!' And he'll be like, 'Oh, you're going to have to woo me.' I think that's romantic in and of itself," shared Jamie, who hosts Married at First Sight: Unfiltered on Lifetime and previously appeared on The Bachelor's sixteenth season.
