birth control
"I've had the implant for 2 months. This past week I was hospitalized for stroke-like symptoms. After several tests it was concluded that the hormones from the implant were causing complex migraines. I don't know why I was not asked if I am prone to migraines, because it would've saved me a lot of trouble. If you are thinking of using the implant, please discuss it carefully with your doctor. No one expressed concern about migraines like they should have with me. If you are prone to migraines, I highly recommend you do NOT have the implant."
