Just need some advice plz🙂💕

So im 15, and on Tuesday I am scheduled to go to a gynocoligest for the 1st time and i am getting birthcontol. I have a boyfriend and i have really irregular and heavy periods so my parents think it will be what's best, and i agree. And i know like it's only 99% affective if you take it right, and like you have to take it at the same time everyday and stuff. But like if you could jist like tell me like how you take yours if you do and like how you stay on scedule and how i can be I can be the safest I can be and like other benefits or like other things I should pay close attention to🙂💕
