If 29-year-old Marianne Barry doesn't take the contraceptive pill each day, she could have symptoms of severe anxiety or even suicidal thoughts.
Marianne has pre-menstrual dysphoric disorder (PMDD), a condition which affects as many as 8% of women and causes intense emotional and physical symptoms in the days leading up to menstruation - with an average wait time for a diagnosis of around 12 years.
Contraceptive medication remains the primary course of treatment for women living with PMDD, but for women who wish to become pregnant this poses a dilemma.
"I want to have a child, but I also want to be sane," said Marianne.
The Welsh government said it was "determined to improve the diagnosis, treatment and awareness of conditions affecting women", including PMDD.
