We are going on holiday in a couple of months. My DD 13 will be due to get her period. She had it the last time we went on holiday. She gets bad tummy ache with it, and it's generally annoying for her to deal with instead of being care free by the pool like she should be. I have been looking at norethisterone as a way to delay her period for a few days. Does anyone have any thoughts or experience with this medication?
