"i got the implanon birth control because i didn&#039;t want to worry about taking a pill everyday. it only hurt a little to have it put in, but really a few hours of pain for three years of peace of mind is a small price to pay.  i&#039;ve had implanon for almost the full three years and here are my pros and cons.  the pros: i don&#039;t have to remember to take a pill everyday, i can have sex anytime and not worry about pregnancy, i never have cramps anymore, my periods are very light and only last a few days.  the cons: my sex drive has gone down to zero (which if you never want to have sex you&#039;re not going to get pregnant) my periods only come every couple of months (there was a span of time where i actually went seven months without a period)."
