"i have been on implanon since november 4, 2011.  as far as birth control, i had only tried the pill which i would forget to take by the 4th day.  the implanon is great in that you don&#039;t have to remember to take a pill everyday.  i have experienced some mild side effects which i can deal with (so long as they remain mild).  i have gained about 5 pounds had one heavy period and feel constantly bloated.  i also have cravings all the time.  i started spotting very lightly last week but it has not turned into a full on period.  after reading the other reviews i have noticed that the people who bleed more are the ones who don&#039;t gain weight. my complexion wasn&#039;t bad before and has actually gotten a little better."
