Hazel Jones was diagnosed with the “one in a million” condition uterus didelphys when she was 18, after suffering with difficulties from when her periods started at 14.
She had to lose her virginity twice, and also has to have two smear tests, but has decided not to have surgery to correct the condition.
The condition means a woman has two separate uteruses, two honeypots and two cervixes. It happens when a septum which usually breaks down between two tubes that form the uterus does not break down, leaving two uteruses.
Ms Jones, from High Wycombe, Buckinghamshire, said nobody realised anything was different about her until her periods started when she was 14.
“That wasn't fun,” she told presenters Holly Willoughby and Phillip Schofield and doctor Dawn Harper, saying she bled from one side then the other.
She was 18 when her first serious boyfriend noticed something was “different”, prompting her to go to hospital where she was diagnosed with the condition.
“As soon as I found out what it was I told everybody! I thought it was amazing. It's definitely an ice-breaker at parties. If women want to have a look, I'm quite happy to show them, it's not something I'm embarrassed by.”
