The most recent episode of the married duo's reality show documented the couple discussing the right timing for having kids of their own.
"I knew my mom had difficulty having me, but I never really knew how difficult it was. Eddie and I have talked about waiting a little bit longer before we try to have kids," the country singer admitted during an interview on the show.
"It had never popped into my head that maybe I will have the same trouble that she did…Given my mom's history, it does make you wonder if I waited too long. If I find out I can't have kids, that will be really tough."
Rimes visited her doctor to see what her chances of conceiving were, and what steps she should take to increase her odds if necessary.
