Mirena
"I had my Mirena IUD inserted 4 days ago. Insertion was somewhat painful; I'm 21 with no children, but with ibuprofen and a long nap after wards I wasn't feeling too bad. Don't be scared; I was sitting on the exam table and almost backed out, so glad I didn't. I did get somewhat lightheaded during the insertion and for about 30 minutes afterwards (luckily I had a friend drive me to my appointment). I had intercourse 3 days after insertion and had no problems! My boyfriend said he couldn't feel it. I've had light spotting off and on and some cramping/backache. Overall, so far so good."
