"i had nexplanon inserted in july of 2014-- so about 7 months ago. the insertion was easy although i had random throbbing pains in my arm every so often afterwards. i was on a routine 29 day cycle with a 3 day heavy period before the implant. the first three months my periods were every two weeks, then every 5, and they were 7-10 days long and heavy the whole time. my moods were all over the place, i had acne, i gained 7 pounds, and my sex drive was destroyed. now, i love it! my periods are light and back to about 5 days- and they come every 40 days ish. my sex drive is back full force- very light cramping- a bit of nausea after any alcohol. otherwise, solid choice-would get it again! bonus, im not pregnant! its doing its job!"
