Birth Control
"Insertion had a sharp pain for only about 15 seconds - I breathed through and it was fine. Cramping afterward, and from then on, my periods were a little off schedule but that was all. This has worked for me greatly. You just have to make sure its in place - my doctor cut the string long enough so I could touch it with my finger. This is a good way to keep track of it without anything going wrong, and so you can catch it if it moves. I have had worry-free sex since I got it. Its a wonderful thing, just be aware of where it is!"
