"i&#039;m on my second implanon. my first one went fairly well. i spotted really lightly for 6 months and then i got a terrible period for 7 days. after that i didn&#039;t have a period for 4 years. now all of a sudden for the past 2 months i&#039;ve been getting my period every 1.5-3 weeks. it&#039;s light, but very random and hard to keep track of.  i give this birth control an 8 because for the majority of my time on it, it did the job. i didn&#039;t gain weight. i only experienced slight acne. and for the most part my mood and sex drive had no change."
