"i love nexplanon. i got it november of 2013. they made sure to numb my arm so insertion was painless. my arm was sore for about a day but no worse than a harsh workout. i did have mood swings in the first few weeks but nothing out of control. then i had my period for about 4 weeks which i&#039;m told is normal. since then i&#039;ve only had a few days of spotting and nothing else. i&#039;m on a nutritionist guided weight loss plan and have managed to lose 40lbs. so far while on nexplanon so no problems with weight gain. i get the occasional acne here and there but again nothing too bad. overall i rate nexplanon high and its so great to no longer have the responsibility of taking a pill every day."
