dd is 16 and she has had periods for nearly 4 years. her cycle is a nightmare - anything between 17 and 70 days. i really thought that it would be settled to a regular pattern by now. She has put on weight and doesnt seem to be as feminine as she was. The other thing that seems strange is that she never uses deoderant but has no 'BO' odour at all. I don't think she swets at all. was thinking of having a chat with gp about it. Have not mentioned this to dd as she is rather sensitive about the weight issue. any one had a similar issue with a teenage dd?
