birth control
"I had my implant on May 28th.  I have not had any issues at all.  I did have some spotting for several weeks shortly after I got it.  I haven't noticed any weight gain yet, but have noticed minor acne.  Not a huge deal.  The spotting did go on for longer than I thought but now has stopped.  I can deal with that rather than a full blown period! I haven't had it long but so far I'm a fan."
