I am a 25 year old woman, married, and have two children. I am currently using a mirena IDU for birth control and its getting close to time for it to be removed. I was trying to find another form of birth control, but I am on medication for my blood pressure. I want something I don't have to worry about getting pregnant, but I don't want something permanent. I am young and i don't think I want anymore children, but whose to say I might change my mind several years down the road. What can I use Rx?
