this, if she doesnt take it like shes supposed to its gonna fuck up her cycle and scare you every month, get on her ass and makes sure she takes it everyday, its not a hard thing to do
sounds like your girl just needs to learn how to take birthcontrol, its honestly not that hard. or she could switch to an IUD and be golden for a five years. but maybe this whole situation has scared her into taking her bc seriusly. can fuck around with that!
