Birth Control
"In April 2010, Implanon was inserted.  In February 2011 I had it removed.  My cycle came about every 2 weeks and experienced breakthrough bleeding constantly.  In short I did not have one day where I was not bleeding.  My doctor said it would go away, I would say I waited too long to give it a chance. I experienced mood and acne.  The excessive bleeding caused fatigue and reduced significantly the quality of my sex life.  It is now July 2011 and my cycle has just returned to normal.  There are good and bad reviews here.  I would say if you are considering this option discuss your entire medical history with your physician.  Perhaps there are some factors that make this a good choice for some women and bad for others."
