birth control
"I'm 34 with no children. Insertion was quite painful. I took tramadol before the procedure and it was still pretty painful---but the whole procedure only took about a minute. I cramped pretty bad for the first 2 days-had to take ibuprofen around the clock. It wasn't normal cramps, more like a intense shooting pain. Now , 5 weeks later, everything is great. 
If I had to have another inserted, I would ask for pain rx to take before the insertion."
