birth control
"Been on Nexplanon since April 2015. Positives: Don't have to worry about daily or weekly birth control regimens. No pregnancy. 
Negatives: Bleeding! Bleeding and more bleeding. My normal cycle not on this drug was at most 5 days. When I first started on nexplanon my cycle was 7-8 days; which wasn't too bad. After 6 months cycle increased to more like 9-10 days and was more unpredictable. Now, almost a year in, I've been on my cycle for 15 days. I'm so over it! I really tried to give this drug a chance to adjust but it seems to just get worse as time goes on. Made an appointment for removal. Good luck! Lol."
