The reality star also opens up to ET about what's changed her mind about marriage.
Bethenny Frankel admits that she had no idea how common miscarriages were among women when she had one herself.
In an emotional interview with ET's Lauren Zima, the Real Housewives of New York star recalls the loneliness she felt after she suffered a miscarriage prior to separating from her now estranged husband, Jason Hoppy. "I never knew how common miscarriages are, and how many women have them and just don't say anything about it," she shares. "I definitely felt like I went through that alone, that was definitely a negative time in my house."
The 45-year-old reality star says at the time of her miscarriage, she didn't want anyone to know what had happened. "Based on things that were going on in my personal life and my marriage, I think that later, I sort of just marketed to myself as that was not meant to be," the Bravo star admits. "Because it would have made things even more difficult than they already were. ...It just wasn't, it wasn't the time."
Frankel -- who did give birth in May 2010 to her daughter, Bryn -- also says she didn't feel like people were talking about health issues on television at the time. "People will talk about money. People will talk on TV about their sex life, they'll talk about infidelity, everything. People don't talk about female issues," she explains. "Women sort of are shameful, or hide things. ...People don't talk about female medical issues to each other a lot."

"I know a lot of people, and I've been through a lot, and it's wild that I really don't know anybody who'd gone through this," she adds.
Frankel -- who tells ET that she believes that her cysts and fibroids may have contributed to her miscarriage as well her "bleeding issues" -- has put a lot of her health and personal drama behind her and, after being separated from Hoppy since 2012, is now in a relationship with New York City banker Dennis Shields. "My personal life is really great. I'm really, really happy right now," she gushs. "Right now I'm experiencing so much happiness in so many different ways, in so many different areas of my life. I do feel like I have a really great balance and I'm really happy."

The Skinnygirl mogul even seems to have a new outlook on marriage. "I said I would never get married, and I said I would never get legally married again. I don't like the idea of a piece of paper being involved in a marriage. I don't like the idea of a prenup. Ironically, no one ever needed one more than I did," she explains. "I don't like the idea of a document, because I do so many contracts, but I have always believed in love. I am a hopeless romantic and I've said -- I said in my book -- I suck at relationships."
Frankel adds that she isn't giving up on the idea of a happily ever after. "People used to think I suck at business and I did and I eventually figured out how to not suck at business," she says. "So, I think that one of these days I will definitely be able to say that I don't suck at relationships."
"I'm ready to let the good times roll now," Frankel insists. "The surgery is past me, hopefully soon my marriage will be past me, and life is good."
