Nexplanon
"I had this implanted in late July 2013 and spotted the next week for a day. I haven't had a period since then until today, which is slight spotting. It is now January 22nd 2014. The insertion was painless (the numbing shot hurt more then the actual implant). The week following wasn't so bad just sore in the insertion area. My Acne has increased a bit about 2x as bad as it was (which was like 3-5 zits and very few blackheads per period). The other problem is the weight gain, In the first two months on it I gained at least 10 pounds. Other than that this was incredibly  convenient. I am super forgetful, hate taking pills, and have a crazy schedule so going to the Dr. was hard. It is incredibly effective though."
