Copper
"I have the Paragard copper IUD for 4 months now, and so for my experience has been average. My only "complaints" are the cramps are at time excruciating! They come "at random" while I'm on my period, nothing I've ever felt before, heating pads, water and physical activity will be your friend ladies. My Dr says the first 3-5 periods will be hard for example heavier bleeding and cramping because the IUD is trying to settle in. Another weird point is that my boyfriend can feel like IUD at times during sex, the string is a little pokey at first but my Dr said it should soften up. I would suggest this birth control for anyone who doesn't want to take pills and doesn't have to worry about it!"
