Looking for advice for my daughter please. She is 15 years old, and started her periods just before her 13th birthday. She’s never been regular but didn’t really notice a pattern. She does a lots of sport, hockey and swimming, and has been tracking her cycle on an app. She showed me the app last night, and her cycle seems to be every other month. I said I’d make a GP appointment, but she doesn’t want me too. Does anyone have any advice? Thank you
