"We were pregnant with a second baby, and at eight weeks I miscarried. And that was a very emotional experience, and it had a lot of different things that came with it," the Bethenny Ever After and former The Real Housewives of New York City star said during a Monday morning appearance on NBC's Today show.
Frankel's miscarriage will not be addressed on the second season of Bethenny Ever After, which will premiere Monday night at 9PM ET/PT on Bravo.
"That is something that has not been dealt with on the show, that is very recent," the 41-year-old reality star told Today co-host Savannah Guthrie.
Frankel -- whose March 2010 marriage to husband Jason Hoppy and May 2010 birth of daughter Bryn were both chronicled on Bethenny's Getting Married?, the predecessor to her current Bravo reality series -- told Guthrie the miscarriage has helped her realize how fortunate she is.
"Thinking about women who can't have their own baby -- even the first baby. I mean, I'm really lucky, I have the most beautiful daughter in the world, and I'm grateful for her. But I didn't know -- until you become a woman, you don't know the things that come with being a woman," she said.
Frankel told Guthrie she is unsure whether she and Hoppy will have another child.
"I'm 41 and I don't know -- it's not really my choice, it's not really my option and the window's closing. And so, you know, it's something that I'm dealing with," she said.
"I'm not really thinking about it, I don't know what I feel that my options are. I do have an incredible daughter, I feel that she's perfect."
In addition, Frankel also acknowledged she is still working through the miscarriage emotionally.
"I honestly, truthfully have thought about other women more than myself. In many cases I don't do that, but in this particular case the first thing that I thought about was, 'Oh my god, I can't believe what people must go through if they can't even have the one.' I mean my baby's still young -- she's 21 months, so I'm still enjoying her being a baby -- and I love that," she said.
"There are so many emotional things that come with it that it's hard to really put into a small conversation. you go through a roller coaster of emotions about it -- about your age, about being a woman, about can you have another baby, about are you a failure to your partner, about what if my husband married someone younger. You go through a million things."
