After a life-threatening bout of preeclampsia in 2010, followed by a miscarriage at 19 weeks in 2011, this has been the longest stretch of time that Michelle Duggar has been not-pregnant in 27 years. So the 47-year-old went to a high-risk pregnancy doctor to see if she's able to have any more kids.

Jim Bob and Michelle don't practice birth control, choosing instead to leave the size of their family "up to God." But on tonight's episode of the family's TLC show, 19 Kids and Counting, the Duggars—who are now grandparents—are interested in a little bit of medical intervention to see "if there are things physically I need to know, that I need to do, health-wise just to be ready to catch a baby if God saw fit to give us one."
