Tia Mowry-Hardrict and her husbandCory Hardrictare completely open to adding to their family, which also includes 5-year-old sonCree Taylor. But there’s one problem standing in the actress and author’s way.

“I do suffer from endometriosis,” Mowry-Hardrict, 37, told PEOPLE at the2016 BET Awards, where she sizzled in Roberto Cavalli on the red carpet. “So there’s a little bit of a challenge there, but I will say this: I am working on my diet.”

She explains that her plan is to follow “a diet I do when I want to just clean myself out and get rid of inflammation in my body.” She also cites her upcoming cookbook,A Whole New You,as something that will help her do just that — since, according to Mowry-Hardrict, “Endometriosis basically grows from inflammation.”

“[We’re] trying, but I don’t want to put too much hope into it,” she adds. “I don’t want to be let down.”

Although Mowry-Hardrict doesn’t want to just assume she will become a mom again, she’s also optimistic about her chances.

“We’re going on vacation tonight to Anguilla, so who knows!” she jokes.

“My son had the best freakin’ party,” Mowry-Hardrict says. “I felt like a really good mom. He turned 5, the whole thing was shark-themed, we had a huge submarine jump tent … incredible food from hot dogs to hamburgers to fries to vegan salad and all different types of treats.

“We had a bubble section, where kids could play bubbles and bubble guns,” she adds, admitting that she may have enjoyed that more than the kids. “My sister and I had more fun in the bubbles. We were shooting each other. It was just great.”

The party was part of a family tradition of celebrating five-year milestones. The next one is her 10-year wedding anniversary, when she plans to renew vows with her husband.

“We want to go to Italy or Europe [this time],” she shares. “It will be intimate. I think it’s important to continue to make it special. So every five years we’ll do a big party for my son and a celebration, renewing the vows.”

So it made sense that, on Sunday, Mowry-Hardrict’s pride for her husband beamed on the red carpet.

“I’m here because of Cory,” she said. “He won the grand jury prize for best actor for theAmerican Black Film Festival. This is a film festival that has putHalle Berryon the map. BET is partnering up with the film festival. I think it’s amazing. They’re giving the African-American community a spotlight to showcase their talent.”
