DD has been having periods for just less than a year now. Most months she gets really, really tired, high temp and quite often also vomits n the first day. I thought we'd helped by making sure she took paracetamol as soon as she felt it coming on, but this month is worse than ever, she just has to take to her bed and sleep. Should I be taking her to the GP - is there anything that can be done? I was never as bad as this, not at that age.
