birth control
"I have had a great experience with this implant.  Getting the rod inserted was not bad, getting the numbing shot was the worst part.  It felt like an intense bee sting.  In the first month I would spot off and on, but it was never anything really heavy.  I do still get a period every month, however they are getting shorter and lighter.  My last period only lasted 2 days.  
I have also struggled with acne since my early teens (I'm now 23), and my skin has never looked better. I think it is important to remember that everyone's body is different.  No 2 of us are the same.  This implant will affect everyone in different ways and there is no way for your doctor to know how your body will react to the implant."
