"i read a lot of reviews saying how terrible the nexplanon was. i would advise you not to freak out about it until you try it. when i saw the reviews it hindered me from wanting to get it but when i talked to my friends that had it, they said they loved it. i am currently 19 years old and have had the implant in my arm for 4 months and i love it! i have had 2 periods since the insertion which i found not unusual after seeing the #1 side effect was menstrual irregularities. also the actual insertion hurt like 6/10 for 2 seconds and it wasn&#039;t even the insertion that hurt, it was the numbing shot they gave that hurt. i could not feel the actual insertion. over all it&#039;s been worth it, you don&#039;t know until you try, you can always have it taken out!"
