Michelle Duggar, mother of 19, heads back to the baby doctor

Michelle Duggar and her husband, Jim Bob Duggar, would welcome the birth of a 20th child, and they’ve visited a high-risk baby doctor to find out what they’ll be up against if that happens.

Highlights of the visit and the reality TV mama’s takeaways from it come courtesy of a new “19 Kids and Counting” video clip exclusive to the “Today” show.

“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,” 47-year-old Michelle tells the camera. “But if there are things physically 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.”

The couple’s 19th child, Josie Brooklyn Duggar, was born 3½ months early, in December 2009. Michelle became pregnant again after that, but suffered a miscarriage in December 2011. The nearly 29 months that have passed mark her longest non-pregnant stretch since before she was carrying kid No. 1, Josh, who was born in 1988.

Michelle Duggar explains that her goal in seeing the high-risk obstetrician was “to really find out where I am in my life right now, hormonally speaking, as well as the ability to carry a baby and give birth, if that’s possible at this point.

“It’s very unusual” to see a pregnancy in someone her age, says the doc,

He notes that at 47, her chance of conception is about 5%, and from there, her chance of having a child with Down syndrome would be about 20% to 25%.

Michelle says the risks are nothing she hasn’t been hearing from doctors since she was 36.

Of course, now her babies are having babies ....
