"i got the nexplanon three months ago. it has worked. i have not become pregnant but i have gained a lot of weight. i gained about fifteen-twenty pounds. it has also caused my skin to be really oily and causes me to get pimples often. i have had my period once in the last three months so i guess that is good. i suggest if you get the nexplanon make sure you are strict at dieting or eating healthy and exercise. i have two meals a day and go to the gym three days a week and have only lost five pounds in one month. the weight came on fast and it is hard to get off."
