"I had my first paragard IUD inserted yesterday. I have never had children, and insertion was painful but not unbearable. I had mine inserted while I was on my period, and I forgot to take any ibuprofen beforehand. There were three steps (opening the cervix, measuring, inserting the IUD) that all felt like quick, hot, fire pokers hitting my insides. It was a sharp, intense pain that lasted seconds. Driving home I had bad cramps. These lasted well into the night. I woke up this morning and the sharp pains were gone! I'm still a little sore, but I think my body is adjusting well. I do not have any abnormal, heavy, bleeding. I'm happy with my decision and I'd say it's worth 10 years of birth control."
