Liza explained how after the initial period as a baby she experienced off-and-on bleeding throughout her childhood, before starting her period “properly” at just eight-years-old.
She said: “My primary school was made aware of it and they had to keep toiletries for me in the reception.
“It helped me to feel a bit more comfortable about it all, I wasn’t made to panic and worry about what everybody 
was going to think. I had a good support system around me.”
But Liza found that as she got older, classmates became more unkind.
She said: “The problems started in high school. At that age you start to navigate relationships, and some of the comments from boys were so personal.
“Even though they have no idea that the reason my body looked so different was because I had been developing since the age of seven, it just makes you feel insecure.
“It was horrible for me to go through school like that.”
But Liza said that her experience helped her to actually come to terms with her changing body far quicker than her peers, and also support other pals through puberty as she had started so much earlier than them.
She said: “It helped me to understand my body.
“I now have a very healthy relationship with my body, and I’m very open to explaining the situation and what I have been through.
“I think a lot of young girls in this day and age are ashamed of their bodies and are ashamed of speaking about periods.
“I want to completely change because I think it’s just the wrong way of thinking.”
Liza said she suffers painful and heavier periods because of her condition, which she manages with the pill.
There was also a risk that it could affect her fertility, although this was not the case for Liza.
According to the NHS website: “Early puberty mostly affects girls and often has no obvious cause.
“It’s less common in boys and may be more likely to be associated with an underlying problem.
“It’s not always clear what causes early puberty. It may just be a tendency that runs in your family.
“Occasionally it can be caused by a problem in the brain, such as a tumour, damage to the brain as a result of an infection, surgery or radiotherapy, a problem with the ovaries or thyroid gland, or a genetic disorder, such as McCune-Albright syndrome.
“Tests and treatments for early puberty can include a blood test to check hormone levels, a hand X-ray to help determine likely adult height or an ultrasound scan or MRI scan to check for problems such as tumours.
“It can be treated with medication to reduce hormone levels and pause sexual development for a few years or treating a possible underlying condition.
“Treatment with medication is usually only recommended if it’s thought early puberty will cause emotional or physical problems, such as a very short stature or early periods in girls, which may cause significant distress.”
