“I want to be as open and honest and raw as possible and that’s why I’m doing this. I wanted to show you guys my journey of becoming pregnant,” the pregnant country star, 34, saidin her latest vlogabout the decision to open up about her past pregnancies with husbandMike Caussin.

“When Mike and I first got together, we were having trouble conceiving, so I went to the doctors and started the process of IVF. We had only three embryos and weimplanted the two embryos. I ended up getting pregnant but we had a very, very early chemical loss,” she said of her first miscarriage.

Fortunately, the couple received good news when “very soon after, I actually got pregnant naturally with Jolie,” Kramer said of her now-2-year-old daughter Jolie Rae.

“Then Michael and I got pregnant last Octoberbut after that miscarriage, Mike and I said, ‘We still have a boy embryo, why don’t we just give it a try?’ This was our IVF journey with the very last embryo we had,” Kramer shared before a series of home videos showing the process of progesterone shots and doctors appointments.

“BecauseI’ve miscarried three times, I just don’t want to say anything. I’m trying to be optimistic but it’s just hard,” the singer admitted before she tearfully announced her fourth loss in another video.

The ups and downs of the process — Kramer had a total of five losses, including three miscarriages and two chemical pregnancies — eventually led to her current pregnancy, which Kramerconfirmed exclusively to PEOPLEin June.

“Just like Jolie, the next pregnancy, I got pregnant again [naturally]. I don’t know if my system needed some of the IVF medicines to hold my pregnancy, I’m not really sure. Butwe are pregnant now. I am almost 19 weeks,” Kramer said in her vlog.

“The times that I’ve miscarried after Jolie, I just remember looking at her like, ‘Man, I’m so lucky to have her,’ ” the soon-to-be mother of two added.
