I tried one of the pills that you only have a period every 3 months and it messed my system up bad! I would still feel like I would have cramps occasionally even though I wasn't having a period, everything on me became swollen, including my boobs - which I wasn't really interested in being bigger in that department, but I would have accepted it, if it wasn't that they hurt so much! And... then I developed cysts on my breast and had to have an ultrasound done to make sure I didn't have breast cancer (at 25!!!). Needless to say, I found out I can only do a low hormone pill, haha.
