Thanks to help from her mom, Martha Stewart, Alexis says she's able to afford the costly medical procedures. "I'm very lucky," she says.
Alexis says her mom also supports her in other ways. "She's very supportive," she says. "She tells me it will happen all the time."
"Because she wants grandchildren?" Oprah asks.
"Desperately," Alexis says.
Right now, Alexis says she does not have a Plan B...she's focused on having a child of her own. "I will [continue] until the doctor says, 'Forget it,'" she says. "When I have to think about my other options, then I will do that. But at the moment, I can only think about this option."
