birth control
"Hello, I first had implanon put in during 2010, I never had mood swings or anything of the sort. I however had a normal period for 11 months and then nothing for 5 months and then a period for a month. I went to my OBGYN they sent me to get an internal sonogram to see what was wrong. They couldn't find anything. But I read someone on one of these forums that changing my diet and exercise would help. And it did. If I exercise 3 days a week and eat relatively healthy I no longer have a period. And it's the same for my Nexplanon which I got put in during 2013."
