birth control
"I got ParaGard as my first form of birth control because I didn't want to deal with hormones. I went through 2 models within 5 months. It turned out that my uterus was too small for the IUD. While I was on it though, the only side effects I had was a slight increase in my period (two days longer and a little bit heavier) and a more sensitive cervix. If my boyfriend even slightly hit my cervix, it would send a jolt of pain up my spine. I really didn't mind it and I wish I could still be using it. I wouldn't worry about the copper. And because it's hormone-free, there is very little risk of having symptoms caused by chemicals (like moods or weight-gain)."
