Like most women, Cassandra Bankson has two eyes, two ears, two arms and two legs.
Bankson, 22, also has two vaginas, two wombs and two cervixes, a fact she discovered last year when she went to see a doctor about nagging back pain.
“When we got the test results back the doctor said I only had one kidney and flippantly added that I have two vaginas -- as she suspected," Bankson told Barcroft TV. “There is one vaginal opening but inside there are two vaginas, two uteri, two cervixes and two fallopian tubes."
Typically, a vagina is one large cavity, but Bankson's was completely separated into two different cavities, a condition known as uterus didelphys.
"I was shocked and the doctor explained to me that it was like an upside nose," she told Barcroft TV. “I didn’t really know what to make of it –- I was just in shock but I don’t really let it get in the way of my life."
Uterus didelphys reportedly affects less than 100 women around the world, according to India Today. According to doctors, the condition represents a uterine malformation, where the uterus is present as a paired organ.
Bankson said discovering she had two vaginas helped explain a lot of issues she had growing up.
“Ever since I was younger I would go to the doctor because I was bleeding for 28 days or I would have two periods a month -– but they never suspected I had a second vagina," she said, according to the Mirror. “It is extremely difficult to deal with because you don't know whether your period is going to last a week or three."
The condition may affect Bankson's ability to have children. Chances of miscarriage, premature labor and underweight babies are high in women with uterus didelphys.
However, in 2011, Rinku Devi, 28, of West Champaran, India, gave birth to twins, one in each uterus.

As surprised as Bankson was to learn of her unique condition, her family was twice as shocked.
"I kind of walked in and said, 'Guess what, mom. I'm twice the woman -- I have two vaginas,'" Bankson told the Daily Mail. "She really didn't know what to say and my dad was really shocked. He's a math guy so was trying to figure out how this would even be possible, but they're cool with it."
So are Bankson's buddies.
"It's no real issue for my friends," she said, according to Cosmopolitan.co.uk. "I just tell them that I'm pretty special but they just see me as Cassy -- not Cassy with the two vaginas."
