"i have had the nexplanon implant for just over two weeks now, and i absolutely love it! there was no pain while being put in, and wasn&#039;t as sore as i thought that i would be. i can&#039;t speak for those who have had weight gain, as i am always hungry and put on a bit of weight from thyroid issues. i feel absolutely no different with this implant in, which is great! i have noticed small blemishes on my back and face, but in order to not have children it is very worth it. so far a great decision."
