birth control
"I had the Mirena inserted in 3/05, loved it, no complaints. 1 tiny one, her name is Gabriella, I found out that while the Mirena was still in I was pregnant (3 years into my 5years).  We were very nervous, I was using the Mirena because of severe possibility of birth defects with medications I was taking. She is our miracle and we have been blessed. The 99.9% effective is very prominent."
