birth control
"I just recently had my 2nd Implanon inserted. I got the first one done in October 2007 and had it taken out November 2010 and a replacement put right back in. Since I have had it in my arm, it is still sore a week later and sometimes feels like it is poking me...sharply. I am hoping this goes away soon. With the first one I didn't have a period for first 2 years and then had maybe 4 a year after. I didn't have really any side effects. Although sometimes I can be irritable a little more easily. It has kept me from getting pregnant for sure. I have 3 kids all conceived on birth control so this is the first to have worked. "
