"i got the nexplanon put in on august 2nd 2012. i didn&#039;t get my period until the next month and when i did it was for about twelve days. i get my period at random times. before this my period was every 28 days but now i have no idea when it will start next. a couple of days after getting it inserted i had a backache for about two days and my hair was falling out; this lasted for a few weeks. now i don&#039;t have any hair loss but around july 16, 2013 i started experiencing lower back pain. i get the pain every single day all day long. it&#039;s a dull ache that just lingers around. overall the nexplanon is very effective. every woman&#039;s body is different; you just have to find the right birth control for yourself."
