“I’m so excited,” the “Dammit” singer, 34, tells PEOPLE exclusively about her happy pregnancy news. “We lost in October and then we did an IVF cycle and we lost in February, so I want to be able to be like, ‘Hey, I know it’s hard but just try to have some hope.'”

Due in November, the country star — who opens up further about becoming a mom again in the latest episode of her podcastWhine Down with Jana Kramer— became pregnant naturally this time after tracking her ovulation cycle with theAva bracelet.

“I didn’t know I ovulated late and I don’t know if it’s because my cycles are messed up because of my miscarriages, but it said I ovulated on the sixteenth or seventeenth day so that’s what we trusted and I got pregnant,” she says.

But that doesn’t mean it’s been all smooth sailing since. Kramer — who’s had a total of five losses, including three miscarriages and two chemical pregnancies — says she’s just coming out of the “worst” morning sickness she’s had yet.

Now with theirrelationship back on track, Kramer has been leaning on her husband during her most difficult days.

“The first [pregnancy] was tough,” she says. “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.”
