As a mother of a 5 year old girl I find it very worrying that when she is 13, a doctor could, without my knowledge, prescribe a hormone implant or pill. As a sufferer of PMDD (severe form of PMS) I understand more than most the delicate balance of female hormones. Messing about with this delicate balance, with hormones that are not bioidentical and especially during puberty is really worrying. This is a poorly understood, under researched area of medicine.
If the law remains unchanged when my daughter reaches puberty I will be writing to my GP to expressly request that my daughter is not prescribed hormonal contraception.
