Hello Dr Samuel, my 15 year old daughter has not had her period for 2 months, we went to the Dr. and she asked all the typical questions and then added that it may be due to cysts, there was no pain at the time we went 1 week ago, but she has just awoken 5am AEST with great pain in her lower abdomen, she has a heat bag on it at the moment which is helping slightly. Do you have any answers on what this might mean?? Sorry, little disappointed, went through the whole procedure only to find out you have to pay for this service....not nice !!
