Let the Duggar family countdown begin.
After revealing on Monday that she's actually six days overdue, according to her husband Derick Dillard, Jill Duggar is now currently in labor.
Derick, 26, announced the big news in a blog post on the Dillard family website on Friday.
"My wife, Jill, is beginning to have contractions which means that the birth of our son is near," he wrote in the post, which is about his understanding of the Bible in relation to his own life-changing event. "I can't even describe right now the anticipation I am feeling, as I am about to get to meet my firstborn son for the first time face to face. So many people have already testified that nothing can quite describe that moment and that I’ll just have to experience it for myself."

He also shared that The 23-year-old 19 Kids and Counting star is currently undergoing labor pains.
"From what I've learned in birth class (as well as from Jill, who is a student midwife) and from what I am witnessing right now with Jill, labor pains start sporadically and then become more consistent, longer lasting, and stronger the closer we get to the birth of our son," he wrote.
However, Jill doesn't seem quite as optimistic that their baby boy is as close as her husband makes it out to be, posting this pic of the couple at lunch on Friday.
"Out to lunch...maybe this spicy Mexican food will make the baby come!" she wrote. "Only Braxton Hicks contractions with this weather so far. We shall see what the weekend brings! #nobabyyet #lunchwithmyhubby."
The birth of "Baby Dilly," as Jill likes to refer to her unborn son, is being documented for the couple's hit reality show. The birth special will air on TLC on May 5.
