At 23 years old, Lorena never suspected a routine checkup with her doctor would begin a two-year journey to post-menopause.
She'd had no inkling anything was abnormal. She was on contraception and was still getting regular periods, so why would she?
But an ultrasound revealed abnormally small ovaries and her doctor advised her to stop taking the pill. Her contraception had masked any symptoms, but as soon as she stopped taking it they began.
Hot flushes, fatigue, mood swings. Her periods stopped.
On No Filter, Mia Freedman speaks to Dr Ginni Mansberg about everything you need to know about menopause. Post continues after.
Perimenopause had begun, but it took two years for doctors to actually figure out what was happening to her body.
"I did all the medical exams that you can imagine... At age 25 finally one doctor looked at me and said what is happening is early menopause," she told Mamamia.
Lorena recalled a rollercoaster of emotions; shock, confusion, anger, loneliness, grief.
She had always wanted to have kids and her first reaction to discovering she couldn't was to cry.
Lorena's relationship broke down and her work became untenable as her employer didn't care about her life outside of the office. There were social issues and her mental health suffered too, and all the while she was physically battling symptoms and side effects from hormone replacement therapies.
"It was a big rollercoaster with periods of deep depression," Lorena, who lived in Brazil before moving to Australia three years ago, said.
"It was complicated. Not just in Brazil, but I believe in the whole world, we live in this patriarchal society where it's very much like, you're a woman, you were made basically to grow up, get married, have kids and that's your life. As soon as you don't have those kids, because you don't want them or you cannot have then, the way that people treat you and look at you changes a lot.
"It was really difficult because I could not understand what was happening inside my own body. So every time someone spoke about having kids, babies or I saw an ad on the TV about a baby, I would cry."
Lorena said talking about her experience - whether in a relationship, or if asked by an unknowing stranger her plans for children - was quite traumatic for years.
There were relationships which ended as soon as she told her partners, and others where men would see it as an opportunity for unprotected sex.
