The couple also shared how they discovered Jill was pregnant just several weeks after they were married.

"When we found out we were pregnant, we were actually at Jill's family's house," Derick said. "She took one of her mom's pregnancy tests and we waited until the next day to tell everyone."

Jessa Duggar and Ben Seewald also have some exciting news of their own, announcing they will be married on November 1st of this year after a four month engagement. In the meantime, Ben has moved in with the Duggar clan.

"He moved up here a few weeks ago," Jim Bob, 49, told PEOPLE. "It has been really good. He has been able to spend a lot more time with Jessa and our family. We have a guesthouse in front of our house, with a shower and everything, separate from the main house."

Jim Bob says he hired Seewald to do work for him while he continues his college courses online.

"Ben was living four hours away in Hot Springs with his parents," Jim Bob continued. "After Michelle and I were talking about it, we have so many projects to do that we need help for - everything from construction projects to keeping the grass mowed to putting roof on a building, paperwork and things like that - and we asked him if he would be interested in moving up here so that Jessa and his relationship could be really accelerated. He was all for it and his parents were happy about it."

However, the couple will continue to have a chaperone at all times and will wait to kiss until their wedding day.

"They always have a chaperone," Jim Bob explains. "It has just worked out great. It is a little more labor intensive for Dad - we did set a curfew. By midnight, every night, we need to make sure everybody is back in their place. Jessa and Ben have set up their own courtship standards. They did not hold hands until they got engaged. After they got engaged, they started holding hands. Just like Jill and Derick, they will be saving their first kiss for their wedding day."

Michelle Duggar agrees:

"Any time you are in love and are together, you realize you want to show your love and affection," she said. "But when you have purposed to keep those protections in your life, you have to remember and have that accountability."

The new season of "19 Kids and Counting" airs on TLC September 2nd.
