Hey

Hey all you girls i need sum advice i am 16 almost 17 and i have never used the Deprovera shot but i wanted to try it because, i dont get my period faithfully on time but i get it and i get some unreal harsh pains when i get it , the pain is so bad i cant sit sumetimes i feel like hurling and i just wanted to know some advice like i want to try it and all but i dont want to end up having my period and this shot being a waste of money does it really work and how longs it usually last for. Thank YOu
