I have migraine problem so my mother says don't take any protection. But I seriously want it because for few years I don't want any kid for completing my eduction . Should I go for f/p shots for birth control or for uterine device for birth control. Plz Plz answer with keep in mind about my migraine. Because I heard it will get worst by taking any birth control medicine or any devices or with shots. Thanks
