"i have had my arm implant since july 5th 2012 and my experience are good and bad. good things are i have not gotten pregnant. the bad things are i have not gotten my period ever since i mean it is good who wouldn&#039;t be happy about that more than 1 year without a period, the bad thing is i think all those things are retained in my body, also i have gained so much weight, i stand at 190 lbs. i have tried watching what i eat, no junk food and exercising, zumba and nothing, not even one pound. i am overweight and it gets me depressed."
