In total, Jana has had five miscarriages, including two chemical losses. However, the mother-of-one is due in November. This pregnancy news also comes just months after Jana reconciled with Mike. Last year, the couple briefly separated after it was revealed he had been unfaithful. Mike entered a rehab facility for treatment and the pair renewed their wedding vows this past December.

"We really wanted to get to a place where we were healthy [before trying for another baby]," Jana explained. "We both know that children do not save a marriage." Jana and Mike are already parents to two-year-old daughter Jolie, and the One Tree Hill alum believes their relationship is back on track. "The first [pregnancy] was tough,” she added. "He was going through his thing that I didn’t even know about, but this time around he’s just truly been the greatest support system I could’ve ever asked for. It feels so much more unified and I love that."

Previously, Jana hinted that 2018 was going to be a big year for the couple — and she was right. "I have NO clue what 2018 has in store for me but I’ve never been more ready to live day by day and enjoy each day as it comes at me," she wrote on Instagram at the start of the year. "Here’s to always believing in love and fighting for it… 2018, I’m ready for you!"
