Nexplanon
"I've been on Nexplanon for about 2 months now and have had zero side effects and absolutely no break through bleeding. I did get my period a week after insertion but I was due around that time anyway... I didn't notice any difference in my period (same cramping, back aches, etc.) other than it lasted for a few days longer. (Normally it's 6 days, this time it was 8). I called my OB and she said to give it a few more months to really regulate.. I'm anxious to see what next month's cycle will be like. I just hope I don't get it on my wedding day! 

Other thing I forgot to mention is that it was 100% covered by my insurance."
