"I am 20 years old, never been pregnant and got the Paragard last year. Insertion was painful but bearable and I was sore for a day or two after. I love how low-maintenance it is and that it lasts so long and doesn't use hormones but ever since I've gotten it inserted, my periods have been longer, heavier, and crampier. Doctor said that for some people, it may go back to normal after about 4-6 months but my periods have remained pretty annoying. I love IUDs but not so much the Paragard. Thinking about switching to Skyla."
