A woman who was born with two vaginas said the consequences of her condition have been severe, and have included long periods and several miscarriages.
The woman, named Nicci, said she first knew something was wrong when she was a teenager, according to the Daily Mail:
I first knew something was wrong when I was a teenager and I was bleeding more than I should. The pain was intolerable and, while on my period, I couldn't function. My doctor told me I had two wombs, two vaginas and two cervixes. There were times when I had to wear adult nappies because tampons and pads weren't enough. The condition has affected my life severely. Relationships with my friends and boyfriends especially.
Doctors ultimately put the woman on hormone treatment, but it did not work and instead made her periods last as long as four weeks.

Nicci later met and married a man named Andy, and is the subject of a BBC documentary called, "The Woman With Two Vaginas."
The condition, known as uterus didelphys, is often something women don't realize they have because it's not always obvious.
"It’s not the type of thing that women find out on their own," Dr. Jason James told Women's Health Magazine. "It’s also fairly easy for a gynecologist to miss it."
A double vagina, he explained, essentially means there's a septum which separates the vagina in half. Though the septum typically divides down the middle, one of them can often become "dominant."

"When the gynecologist examines the patient, the speculum more easily goes into the dominant vagina," James said. Doctors often miss the condition if they're not paying close enough attention.
According to World Health Organization estimates, approximately one in 3,000 women are affected by the condition, which occurs when the uterus fails to fuse properly during development in the womb, the Daily Mail reports.
YouTube star Cassandra Bankson is another woman who recently discovered two vaginas after a trip to the doctor, according to Women's Health.
"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," she said in a video clip.
"Most of the time this condition is only discovered when the woman is pregnant and has a scan or during childbirth. Generally there is no reason for her or anyone else to [realize] that she has it and really at 1 in 3000 it is not all that rare," one Daily Mail reader commented.
