"I have been trying to get pregnant for over a year and a half. I'm willing to try different things," Montag added. "It's a great source of nutrients. I have felt incredible on this diet. A lot more energy, clarity, increased libido and overall improvement on chronic pain I have had. Also, now I've been taking the supplements called 'Her Package' from Heart and Soil that has improved my menstrual cycle."

In August 2021, Montag had non-cancerous uterine polyps removed to help with her fertility issues.

"I was feeling nervous last night about it, but I'm excited today," she said in a YouTube video at the time.  "And I'm hoping that the surgery works and that this is the only reason I haven't been able to get pregnant."
