"i got my nexplanon may 14th 2015... the insertion wasn&#039;t as bad as i thought but when i got the shot to numb my arm , it burned pretty bad. after , i bruised for a week and could not hold anything heavy in my hand without my hand shaking and the item falling for about 3 days. i kept the gauze wrapped for much longer then 3 days. once i removed it , i bruised again. (then again i have a fairly light complexion) the week after i had constant headaches (i almost never get headaches) and frequent break outs, and mood swings especially with the implant and my period combined. one moment i&#039;m mad and the other i&#039;m laughing about it. but it&#039;s been almost 3 weeks and i no longer have headaches or break outs other then i normally used to have. but i have been having that &quot;end of the period blood&quot; for six days now. extremely annoying!  the on the edge anger still remains but i think it&#039;s helped me speak my mind more easily lol i&#039;m 19 and could never get past 120 lbs. , i now weigh 135. and i&#039;m so excited for the weight gain, just hope it&#039;s not excessive!!!! oh and i do feel bloated and tired sometimes..but i gave it a 9 for not having to remember the pill and 99% effectiveness towards not getting pregnant"
