"i had the nexplanon implant inserted in january and for a couple of months it was great. i didn&#039;t have any bleeding or cramps for about the first 2/3 months. then i started having my period and it would last around 3 weeks. the first time this happened, i was annoyed but i thought maybe it was just a one off thing. then about a month later, my period started again and lasted for 3 more weeks. i&#039;ve called my doctor and they say it&#039;s nothing to worry about, but it&#039;s incredibly annoying to be on your period for more than a week. i&#039;ve spent more time in the last 5 months on my period than off it. my doctor has recommended i try a birth control pill to regulate my periods, but i wouldn&#039;t recommend nexplanon. it&#039;s not worth the hassle."
