birth control
"I am 23 no kids. I got the IUD over a year ago and I am experiencing changes in my period. They last 7 days when they used to last 3. I get horrible cramps and discharge a week before them. They have also changed in dates. Mine used to be around the first of the month now they show up whenever they feel like it. The only plus side is that I am not pregnant but that's only because I can't have sex due to the long periods and weird cramping and discharge."
