My 15 year old daughter has a headache almost every day, stomach pains (not necessarily stomach but can be all over in different places and different kinds of pain, sometimes shooting pains sometimes constant), dizziness often associated with headache and stomach pain. Irregular periods sometimes misses for a month or even two months and then has really heavy and painful period. Has missed 30 days of school this year. Is absolutely not pregnant. Has already had gallbladder checked and that's fine. I think her problems are hormonal if you can help in anyway I'd really appreciate it I'm at my wits end and really scared there's something seriously wrong. Taken her to the doctor many times no one can find anything wrong. mommyles101
