"She cannot drive a car, buy alcohol or tobacco, or have sex, but she can have a contraceptive implant without my knowledge."
The publicly acknowledged side-effects of the implant included headache, nausea, mood changes, acne, pelvic pain, vaginal inflammation, varicose veins, hair loss, excess hair growth, ovarian cysts, a breast discharge, weight gain/loss, back and general pain. She did not specify the effects on her daughter, but said they had been marked.
Three weeks after the implant was removed, she got her "real" daughter back.
She also questioned how an implant could be approved without access to the child's medical history, and that of her family, adding that the clinic had also prescribed a contraceptive pill to her daughter.
The implant had been removed at her daughter's request - her parents discovered that they had no legal right to ask for its removal - "It was totally out of my control," she said - but the experience had caused the family deep distress.
"I was lucky that my daughter told me, otherwise I would never have known," she said.
"She thought she was doing the right thing, but she had a number of the side-effects mentioned, including a marked change in personality.
"How and why this centre can do this without a parent's knowledge is unbelievable," she added.
"To all parents of teenage girls, beware of what this centre can do. I wonder how many other 13-year-old girls have had this implant put in and have not told their parents."
