I started taking the pill when I was 13 for irregular periods I stopped after 3 years because it was not regulating at all. I became sexually active when I was 14 so that's the main reason I stayed on it. After I stopped taking them back in 2015 I started using the nuva ring to see if it would help regulate my period even though I was sexually active and needed it I still needed my period regulated. after 2 years of using it I still haven't had a normal period. So I quit using it and I went to the doctor at the beginning of this week and they offered the shot I didnt know anything about it so I said let's try it and I'll come back in 3 months and determine if I want to stay on it or stop using it. I don't know much about it so can someone help me learn a few things. I've looked things up but I get told the same stuff on each website. Can someone tell me some things to help?
