"The morning after we announced to family that we were expecting, Jinger woke up and, woke me up very early in the morning, saying that she thought she lost the baby," Jeremy told People. "We found out later that day that she had. That was very difficult and definitely a trial for us."

But the Vuolos are reportedly "overjoyed" about the news that Jinger is expecting again.
