The Counting On star and his wife Lauren reveal they suffered a miscarriage in October

Josiah Duggar and his wife Lauren are opening up about their heartbreaking loss.

In PEOPLE’s exclusive sneak peek from the new season of Counting On, the TLC stars reveal they suffered a miscarriage in October.

“Lauren and I were actually preparing for a trip to go to a friend’s wedding,” says Josiah, 22. “She started feeling really sick and started noticing some different things. Mrs. Swanson was there, so she was able to help her out. I didn’t know exactly what was going on.”

“I wasn’t feeling well,” recalls 19-year-old Lauren, breaking down in tears. “I was cramping really, really bad, which was quite strange because I normally don’t. I was thinking maybe I had something that had gluten in it. It was late at night and I went to use the restroom and there was the baby. Gone. I couldn’t believe it and I was hoping it wasn’t true.”

The couple got engaged in March 2018 and married on June 30 at John Brown University Cathedral of the Ozarks in Siloam Springs, Arkansas.

“We are overjoyed to begin this new phase of our lives together,” Josiah told PEOPLE in January. “Through the years our families’ friendship has allowed us to get to know one another as friends. I can definitely say I have found a great friend … even better than I could have hoped for or imagined.”

He continued: “I so appreciate Lauren’s Christ like character and tender heart toward others. She bring sunshine into the room and encourages everyone around her. It’s always stood out to me that in every situation, she looks for the one who appears to be sad or lonely and quickly can brighten their day by sharing words of hope, an encouraging scripture, a prayer or even a simple smile with them.”

Counting On returns Monday at 9 p.m. ET on TLC.
