Moon admitted that, if asked, she may not return to the Bravo hit reality series for a second season given her busy schedule as an anesthesiologist and mom of two.
"Something would have to change," Moon said on Monday's episode of the PEOPLE Every Day podcast, hosted by Janine Rubenstein. "I cannot do the show if everything is exactly the same as it was this year. I am still working four days a week. My children are now a little bit more demanding than they were when they were younger. Something's gonna have to give. Like, I only have 24 hours in a day."
The anesthesiologist explained that she doesn't "know what's going to happen" with her future on the show, which wraps its fifth season in the coming week.
"I've not even been invited back ... I don't know what's happening either," she told PEOPLE. "So I'm just gonna take it one day at a time. Like the advice I give to my medical students and residents, you know, when they're having a bad day, I'm like, 'you know, one day at a time, one day at a time.' So sometimes I have to give that advice to myself too."
Tiffany also revealed how she feels about filming the show's reunion. "I'm nervous just because I haven't ever done it before," she said. "Sounds like it can be a long day. I'm nervous to meet Andy [Cohen] ... I've never breathed the same air as Andy. I have not seen the majority of my castmates or spoken to the majority of them since we wrapped filming, which was more than six months ago. Maybe just like a text message here and there, but not in the same room talking."
"So yeah," Moon added, "I'm nervous because I think there is a lot to unpack."
Moon shares 6-year-old twin daughters, Chloe and Madison, with husband Daniel Moon. She's also stepmom to Daniel's teenage twins, Nathan and Nicole. During her time on the show, Moon has been vocal about wanting to make more time for her family due to her hectic anesthesiologist career.
