In a YouTube video posted Saturday, Arie and Lauren revealed in a nearly 30-minute video that she suffered a miscarriage weeks after learning she was pregnant. The video description reads, "A little over a month ago, we got the most exciting news and we found out that we were pregnant with our second baby. We made so many plans. We bought a new house with more space, we planned how we wanted to tell you all and we envisioned our future with Alessi’s little brother/sister."

It continued, "We were planning to share our journey through pregnancy with you, but unfortunately we didn’t get the happy story we had hoped for. We decided to share this part of our journey with you, because well, we share everything with you! But also because we hope that by talking about this we can make other couples going through these times a little less lonely."

The video started with Lauren pulling a prank on Arie in which she marks a pregnancy test as positive, only to find out with another test that she actually was pregnant.

They explained that they were filming a video where Arie "accused" Lauren of being pregnant, but she "didn't think I was," only to realize she "pranked myself."

Lauren smiled in the video as she held their daughter Alessi, saying, "I guess we'll be a family of four pretty soon."

She went to the doctor for an ultrasound, and the doctor told her she looked to be about five weeks along, which surprised Lauren.

Lauren said, "At that point, I should’ve been eight weeks, and the ultrasound showed that I was five weeks, so we were really confused by that. Our doctor assured us it could be a number of things and not to panic."

Arie and Lauren felt "reassured" after a blood test revealed that Lauren’s hormone levels had risen to a "proper level."

At another ultrasound, the doctor noted her fetus was still "really small," dating it to six weeks. Lauren said, "We got more bad news. The baby was only measuring five days more than it was in the previous ultrasound, which had been two weeks prior."

The saddest news of all came when Lauren went to another doctor and Arie sat in the car on FaceTime as the doctor revealed to Lauren that she miscarried. Lauren said she didn’t see any blood, but the doctor explained she suffered a "missed miscarriage," which is "the most common kind."

Their doctor said, "Your body hasn't recognized it yet. You still have hormones like you're pregnant."

Arie said, "It’s been a roller-coaster of emotions, going from scared at first to happy then stress and worry for weeks on end, and today was the bad news. It’s something you can never really prepare for. I feel like it’s something we’ve been trying to prepare for, either good or bad news, but trying to stay positive at the same time."

He continued, "It’s consumed our thoughts for the last month. It’s hard holding this back from everybody, because we feel like we’re on here all the time talking about our day and our lives."

Lauren said, "Trying to be on social [media] all the time pretending like nothing is happening is really hard. It makes me so anxious hiding something like this. I was really excited to tell you guys that we were pregnant."
