I can't quite get my head round it but my 11 year old has started her periods. She's had the discussions at school and we've talked about it at home so she was more prepared for it than I was and has taken it in her stride but this is her second month now and she is feeling sick and has slight stomach cramps. Not sure what pain relief to give I can't imagine Calpol will work its wonders on this one and having used it for the last 11 years I'm completely lost. I don't want to start over loading her with paracetomol at this age Any advice?
