birth control
"I'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't have a period for 4 years. Now all of a sudden for the past 2 months I've been getting my period every 1.5-3 weeks. It'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't gain weight. I only experienced slight acne. And for the most part my mood and sex drive had no change."
