birth control
"I got the Implanon on September 3 2010 and so far I have had mood swings like crazy and had my period for 1 1/2 weeks (normal for me is 3 days) and spotting for another week. My libido has been revved up. So far I think it is okay...but with the whole libido boost and the constant unprotected sex...wondering how likely I am to get pregnant."
