"i got my implant in august of 2013. i have not had any problems with it. i stopped having a period until not the next january but the one after. i bled for the entire month, but i was not upset about it because over a year without a period, i&#039;ll take bleeding for a month. haha :) yeah, i&#039;ve had some spotting here and there but nothing that has really effected me. i didn&#039;t experience any weight gain. (and i have to say, birth control doesn&#039;t make you gain weight. it increases your appetite, so if you eat healthy you would be fine.) i absolutely love nexplanon."
