"effectiveness i assume is fine. i had the implant inserted october 2016, but at age 45 i&#039;m not fond of the 2 week cycle/spotting, 1 week of nothing and back on to spotting. i took birth control pills for years and my cycle would run 3-5 days every 28 days like clock work. i didn&#039;t have an issue forgetting to take them cause i took them when i took my other meds. my doctor was concerned more about blood pressure/stroke possibilities.  this birth control though is not for me. i was told a few months of bleeding then nothing at all. its been 7 months and 4 phone calls and i&#039;m beyond frustrated. made an appointment to have it removed next week. disappointed to say the least."
