"i got nexplanon implanted a little over a month and a half ago and i am loving it. after inserted it bruised and hurt like anything  but that was over in about 3 days. then 2 weeks after i got it inserted i got my first period (i was supposed to have my regular period 2 days after insertion) and it was okay. it went just like my regular period lasting 4 days but i didn&#039;t have and cramping or major break outs during this time like usual, the only thing that was different was i spotted for 6 days after that. i haven&#039;t gained any weight, no acne, no cravings, no mood swings, nothing at all. i&#039;m a 19 year old who weighs 145lbs."
