birth control
"I am 51 year old on my 2nd Implanon device; the first one replaced at 3 years as recommended.  I did gain some weight, but it's more a water retention thing.  I used to have very painful periods, which is why my GYN recommended it.  I'm one of the lucky ones.  Have not had any periods in 5 years, (spotted a bit the first month only) and plan to continue to use the Implanon until I'm completely menopausal (still perimenopausal).  The only reason I can't give it a 10 is whenever my blood pressure is taken in the left arm, the implant site "pinches", solved by having BP taken on the other arm, but I was told I shouldn't be able to notice it.  Cost a bit up front (even with insurance), but saved on prescription co-pays for 3 years so still cost effective."
