My 16 my old has been having a nasty tummy before and during her period. Am I unreasonable for not wanting her to take the pill because of health reasons? My family, unfortunately are prone to cancer, when a relative has died its usually cancer related, therefore I don't want my daughter to take something that could provoke cancer. We have been to doctor and the medication he prescribed did not work. Is the pill the only answer? Surely there's something else?
