"i&#039;ve had my implant for 2 years now. when i first got it, i was finishing out my menstrual cycle &amp; asked the heath care provider if it was going to be an issue. i was told that my cycle would be fine. i spotted on &amp; off for 3mo. but after, i was having cycles regularly. then, i was bleeding for a month straight. after that, i didn&#039;t get my next cycle for 4 months. during that time, i had switched jobs &amp; was working around alot more females than originally. i&#039;ve been an emotional wreck the entire time &amp; have had terrible mood swings. it&#039;s effective with not getting pregnant, but it takes an emotionally strong person to deal with the side effects of it. wouldn&#039;t recommend for everyone, but it is good for a changing schedule everyday."
