"i have had nexplanon in since march 2013 and i really love it. i had a regular period (5 days) a week after i got it put in, and since i&#039;ve only spotted twice, each so light i only had to use a liner, and only lasted for a day. but, i&#039;ve gained about 15 pounds (no appetite change, that&#039;s the weird part) and had to start using acne face washes (not bad, i just wash my face with it in the shower and then use an oil free moisturizer). overall, i think its great and such an easy process putting it in, and then you don&#039;t have to worry about it. i recommend it highly, but be prepared to have a few side effects."
