birth control
"I chose Paragard because I had rough side effects from hormonal birth control. I was also not sure if I wanted more children, probably not due to my age and health problems I had with my last pregnancy, but just in case I changed my mind I didn't want to choose something permanent. Imagine my surprise when I became pregnant on Paragard. An ultrasound showed it was correctly positioned. I was relying on Paragard to be as effective as advertised. Now, looking online, I see that thousands of other women have had this happen as well."
