My daughter first started her period when she was about 12 but I have recently noticed that she has not been using any of the sanitary products for months now I have tried many times to speak to her about this but she says I'm disgusting and to stop talking about it I'm worried that her period has somewhat stopped or there is a problem I know she is not sexually active before anyone says she might be pregnant that would be impossible as she is very quiet and reserved and does not socialise or go out she goes to school and that's it she spends all her time with me in the house I'm not sure what to do about this as she just won't speak to me about it at all says I'm disgusting and rude.
