birth control
"I love my IUD for many reasons. A lot of these reviews are just based off of the initial side effects and insertion. While I admit it was mildly painful for the first 24 hours and the spotting lasted 1-2 months, I am now 3 years in, and couldn't be happier. My period is 95% lighter and lasts only an hour, I never get cramps anymore, and I am comforted by the fact that it is so reliable! No weight gain or mood changes and my skin is still clear. Some people say these cause infertility but that is not true. IUDs have undergone many many clinical studies which show that is not the case! Don't let people on here scare you :) If you want the facts, go to a credible source. http://www.sciencedirect.com/science/article/pii/0010782485900484"
