Mirena
"I have had mirena for 2 years now, and I can say that its the best birth control. I had minor cramping and bleeding when it was implanted. Nothing major. I love knowing its in there and I don't have to remember to take anything. I have no periods, maybe one really light one every 8 months, I do have breast tenderness and sometimes minor cramps. I plan on having one more child within two years which I will get it taken out. It was a one time cost and nothing monthly. My insurance did cover it so I only paid 35$ co-pay. But I would have paid the full price for sure. Hope this helps!!"
