Michelle Duggar, the famous mom in '19 Kids & Counting' is now longing for another child to join her ever-growing family, even at the age of 47, People has learned.

Michelle Duggar, for the most part of her life, has been pregnant with her 19 kids, and now that she's 47, she still plans to have child no. 20 join their big family.

Duggar currently has 18 kids staying with her in their home, and she is already a grandmother to three young kids, but she feels the need to have another child to make her family complete.

Duggar is reportedly desperate, so she visited a fertility doctor with her husband, 48-year-old Jim Bob, as shown in the all-new episode of '19 Kids & Counting.'

"Conception is not totally impossible, but most unlikely," Michelle says in the clip, which also shows her getting blood work results.

According to Michelle and Jim, the number of the children they have is in God's hands. Currently, they have 19 kids ranging in age from 4 to 25, with five below the age of 10.

The Duggars' youngest child, Josie, was born prematurely but as of writing she is already in good health. In 2011, Michelle Duggar and her husband got the saddest news of losing their 20th child to a miscarriage.

The husband and wife told People back then that they were mourning for the loss of their 20th child, whom they named Jubilee Shalom.

"We've always put this in Gods hands," Jim Bob said in the all-new episode of Michelle's plan for more children. "And if God wants to give us more children, we are going to be happy either way."

Michelle Duggar and her husband have always believed that if it's God's will then the former could be pregnant. They also said that they trust God wholeheartedly, that He will provide for their family all the time. Hence, they do not use contraception and they simply put everything in God's hands, the Christian Post reported.

'19 Kids & Counting" airs on TLC at 9 p.m. ET every Tuesday night.
