"i have had implanon for about 3 months. it was very sore for about a week after insertion. it has also moved almost the full length towards my elbow so i&#039;m am going to get it checked. i have not had a period since i got it inserted. i have ups and downs with mood swings. the first month was the worst. since then i will randomly get upset or mad and have recently been breaking out a lot which is not normal for me. i also have had bad headaches. it is very convenient but there are a lot of side effects. i am going to put up with it and see if they improve after 6 months. i prefer the patch which i had no side effects but it was more expensive."
