'19 Kids And Counting': Michelle Duggar Gets Upsetting News At A Prenatal Check Up (VIDEO)

Unlike some of her earlier pregnancies, Michelle Duggar's latest pregnancy has been chronicled publicly almost from beginning to end. She and husband Jim Bob announced the news that she was pregnant with her 20th child live on the "Today" show back in November, and cameras followed her to prenatal doctor's visits.

Thus, viewers of "19 Kids And Counting" (Tue., 9 p.m. EST on TLC) watched as Michelle and Jim Bob received the news that no expectant parent ever wants to hear -- the doctor could not find the baby's heartbeat.

Twelve weeks pregnant, Michelle had gone in for a routine check up when her doctor asked if she wanted to hear the baby's heartbeat. However, the doctor couldn't detect it on the doppler, and the situation was tense as she sent Michelle for an ultrasound scan.

Finally, they received good news: The baby was okay. Michelle and Jim Bob were overjoyed.

As everyone knows, Michelle went on to have a miscarriage at around 20 weeks. The moment that the Duggars heard the devastating news will feature on an upcoming episode of the show.

"19 Kids And Counting" airs Tuesdays at 9 p.m. EST on TLC.
