"i&#039;ve had nexplanon in for two weeks and i&#039;m pleasantly surprised so far. today i started spotting, very lightly. i haven&#039;t gained any weight, i&#039;ve actually lost, but i eat right and exercise. my doctor explained to me that i may feel hungrier at times because of the increase in estrogen, and at those times i just need to remember to make the right food choices. i have had a slight increase in acne, and i asked my doctor about that before i had the implant inserted. she told me that my skin will start producing more oil, which i have noticed. so all i did was buy some oil absorbing face wash and toner, and it&#039;s been great since then! those were my three main concerns, my doctor was great at explaining to me why those things happen."
