birth control
"This was the best option for me. I'm terrible at remembering to take pills. I've had the Implanon for 30 months and for the first 6 months my periods were regular for me. Then for the next 23 months I had no period. Then this last month, I've had four periods. First two were a few days on a few days off. The the third one was 8 days and I'm currently on day 3 of the 4th one. 
No pregnancies
Some mood swings 
Minimal sex drive
No weight gain
I also didn't take any other medications while I've been on it, except for the occasional Tylenol for minor headaches."
