Eight is not enough for Michelle and Jim Bob Duggar—and neither is 19, apparently. A new preview from the upcoming episode of the couple’s TLC reality show, 19 Kids and Counting, finds the Duggars seeking advice from a fertility doctor about whether it’s safe and possible for Michelle, 47, to get pregnant again.

“We are just going to check and see that I’m physically in good condition,” the perpetually pregnant mom says in the clip. “We would love more children if God saw fit to give us more—I just want to make sure that I’m ready to catch a baby if that would happen.”

With that in mind, Michelle and her husband travel to Little Rock, Ark., to consult with Dr. Paul Wendel, a doctor who specializes in high-risk pregnancies. “If I am in that season of life where we’re not able to have any more, then I’m fine, I’m happy with that,” she tells him. “But [we’re here to see] if there are things physically that I need to know, that I need to do, healthwise, just to be ready to catch a baby if God saw fit to give us one.”

Michelle most recently gave birth in 2010, following a life-threatening bout of preeclampsia. The next year, she got pregnant again—only to suffer a miscarriage at 19 weeks. The three years since are the longest stretch of time in 27 years that she has not been pregnant.

“We do occasionally see pregnancies in women who are 47, 48, 49, even 50,” Dr. Wendel tells the couple. “But they’re very unusual—very unusual.”
