Iv been on implant for 9 years had no issues with it at all no side effects so when three years was up I got another in yep same again no issues or side effects well unless having no period is a side effect I call it a bonus ? After 9 years I removed it in Dec to try for baby THEN got pregnant in the July had healthy baby boy the following April . It's normal to have no periods on the implant or your one of the unlucky people who bleed a lot and it's just not for you ?
