"i am giving it a 5 because as far as being effective goes... it was very effective. i first had the implanon for 3 years and then was placed on nexplanon. i just had it removed yesterday, the 3 years is up shortly. i have had issues with irrational mood swings. to the point that i thought i was bi polar and needed to be diagnosed. it has caused strain on my relationships and has made me feel awful about myself. i got it removed after doing research about what could be causing these mood swings and found out there are hundreds, probably thousands or more, of people who have had the a similar situation. i am hoping that now that it has been removed i will start to feel better soon."
