"The good: Implanon was 100% effective, and very convenient. The bad: It killed my desire for sex completely. I gained 30 pounds within two months. I have a history of migraines, usually getting them every couple of months, but during the last six months of having Implanon, I was getting them twice a week, with bizarre symptoms. My migraines would make me feel like my face and entire left side of my body was numb. I would forget words, I would have trouble forming sentences. Sometimes it felt like I was totally disconnected from my body, and that my head was caving in. My doctor sent me to get an MRI, but nothing was wrong, and they diagnosed "complex" migraine. Had Implanon removed 2 months later, and the weird migraines stopped."
