Copper
"I've had my paraguard in for about a month now and I have to say it was the best decision I have made. I was EXTREMELY hesitant about the insertion and the aftermath. The night before my appointment I got no sleep at all due to being so scared...especially after seeing all the negative reviews and horror stories. When the time came, my hands were sweating and shaking, I was petrified. It literally took about 30 seconds and I hardly felt anything. A very mild cramp and it was over. I've had period cramps that have been much worse than that. Afterwards I was expecting to be in pain all day and just be fishing blood. Neither happened. No cramping at all and the blood was so mild that it didn't even fill a panty liner. I highly recommend it!"
